fix: misc fixes for pdf-server, map-server, and say-server (#329)
* fix(map-server): simplify location update message format

* fix(say-server): pass host to streamable_http_app for non-localhost deployments

* refactor(pdf-server): simplify to stateless range-query architecture

- Remove caching/indexing in favor of direct HTTP Range requests
- Use HEAD requests to get file size (no full download)
- Use Range requests to proxy byte chunks (no caching)
- Local files: fs.read with offset/length
- Remote files: HTTP Range header
- Zero memory footprint (no PDF caching)
- Truly stateless (no session management needed)
- Single server.ts (~350 lines) + main.ts CLI entry point
- Instant startup (no preloading)
- Security: whitelist local files, allowed origins

Removed files:
- src/pdf-indexer.ts
- src/pdf-loader.ts
- src/types.ts

* feat(pdf-server): add dark mode support

- Add CSS variables with light-dark() function for automatic theme switching
- Sync theme with host via applyDocumentTheme()
- Apply host CSS variables via applyHostStyleVariables()

* feat(pdf-server): add list_pdfs tool back

Lists local files and allowed remote origins.
Also moves CHUNK_SIZE to module level constant.

* feat(pdf-server): improve tool descriptions and increase context limit

- display_pdf: list all allowed domains in description
- Increase MAX_MODEL_CONTEXT_LENGTH to 15000
- Move CHUNK_SIZE to module level constant

* chore(say-server): remove deployment docs from repo

Keep server.py fix for non-localhost deployments.
Deployment docs kept locally but not in repo.

* refactor(pdf-server): simplify updateModelContext format

- Add widget ID for multi-widget disambiguation
- Use concise header: 'PDF viewer (id) | title | Current Page: X/Y'
- Add 'Page content:' prefix before text
- Keep selection markers (<pdf-selection>...</pdf-selection>)

* refactor: rename widgetUUID to viewUUID for consistency

Aligns with main's standardization on 'view' terminology (PR #325).
Also dynamically generate allowed domains in display_pdf description.

* viewUUID

* fix(map-server): fix syntax error in location update message

* fix(pdf-server): restore package.json, improve server docs

- Restore --external pdfjs-dist in build
- Rewrite server.ts header for newcomers (list tools, not implementation details)
- Minimize main.ts diff

* chore(pdf-server): remove unused addAllowedOrigin/addAllowedLocalFile

* docs(pdf-server): update README for new architecture

* docs(pdf-server): restore full README, add theming section, remove get_pdf_info

* rm

* fix(pdf-server): restore createMcpExpressApp and error handling

- Use createMcpExpressApp for DNS rebinding protection
- Restore error callback in app.listen()

* fix(say-server): pass host to streamable_http_app for non-localhost deployments

fix(examples): improve updateModelContext with structured YAML frontmatter (#271)
* map-server: fix async/await in ontoolresult, remove unused getViewStorageKey

* fix(map-server): improve updateModelContext and fix initialization

- Use structured YAML frontmatter format for model context (like pdf-server)
- Add tool name, altitude, and cleaner data format
- Fix initialization deadlock: app.connect() was inside ontoolresult handler
  which could never fire until connected
- Fix view state persistence: widgetUUID now properly extracted from
  ontoolresult and used to restore persisted camera position
- Server now includes widgetUUID in tool result _meta for widget identification

* fix(pdf-server): use widgetUUID for page persistence

- Add widgetUUID to tool result _meta for widget identification
- Use widgetUUID instead of generated key (pdfUrl+toolId) for localStorage
- Enables reliable page restoration when revisiting PDF widgets

* fix(transcript-server): use structured YAML frontmatter for model context

- Add tool name, listening status, and unsent entry count in frontmatter
- Consistent format with pdf-server and map-server

* update names

* drop bogus altitude

* Update mcp-app.ts

refactor(map): use app.updateModelContext() instead of adhoc request (#245)
* feat(map): add keyboard shortcuts for fullscreen control

- Escape: exit fullscreen when in fullscreen mode
- Ctrl/Cmd+Enter: toggle fullscreen from any mode

* feat(map): persist view state to localStorage

- Save camera position/orientation on moveEnd (debounced 500ms)
- Restore persisted view when no explicit tool input is received
- Key by toolInfo.id (tool invocation ID) - localStorage is per-conversation
- Tool input (explicit bbox) takes precedence over persisted state

* refactor(map): use app.updateModelContext() instead of adhoc request

* comment out app.registerTool call for now

* prettier

* fix error handling in server-utils.ts

* refactor: rename cesium-map-server to map-server

- Rename examples/cesium-map-server to examples/map-server
- Update package name to @modelcontextprotocol/server-map
- Add README.md with documentation

* style: add min-height of 400px to map container

* feat(map-server): add fullscreen support, clean UI, sharp rendering

- Add fullscreen toggle button (only shown if host supports it)
- Use autoResize: false and manually send height of 400px
- Hide Cesium UI controls (home, scene mode picker)
- Remove location label (gets stale quickly)
- Use full device pixel ratio for sharp rendering on high-DPI displays
- Resize Cesium viewer when display mode changes

* feat(map-server): add reverse geocoding (logging only) and rounded corners

- Add camera move end listener for reverse geocoding
- Debounce Nominatim API calls (1.5s) to respect rate limits
- Log location name to console on camera move
- Add nominatim.openstreetmap.org to CSP connectDomains
- Add 8px rounded corners to map container

* fix(map-server): fix pixelated rendering on high-DPI displays

- Set canvas imageRendering to 'auto' (CesiumJS defaults to pixelated)
- Set resolutionScale to window.devicePixelRatio for native resolution

* tweaks

* update model context w/ current location

* fix(map-server): improve rendering quality and add visible extent logging

Rendering fixes:
- Remove incorrect resolutionScale = devicePixelRatio which was doubling
  the scaling factor on Retina displays (2x2=4x), causing blurriness
- Disable FXAA anti-aliasing which can cause blurriness on high-DPI displays
- Keep useBrowserRecommendedResolution: false to use native devicePixelRatio

Reverse geocoding improvements:
- Add getVisibleExtent() using camera.computeViewRectangle() to get the
  visible bounding box (west, south, east, north)
- Add getScaleDimensions() to calculate visible area in km
- Add calculateNominatimZoom() to map visible extent to appropriate
  Nominatim zoom level (3=country to 18=building)
- Log visible extent with dimensions on each camera move
- Pass zoom parameter to Nominatim for context-aware geocoding results
- Update model context with visible area dimensions

* fix(map-server): direct positioning + wait for tiles before showing

Changes:
- Remove zoom granularity logic from reverse geocoding (was not working)
- Keep extent logging in both console and model context
- Replace flyTo animation with instant setView positioning
- Add waitForTilesLoaded() to detect when tiles finish loading
- Keep loading spinner visible until:
  1. Tool input positions camera to destination
  2. Tiles at destination are fully loaded
- Add 5-second fallback timeout if no tool input received
- Add 10-second timeout for tile loading to prevent infinite wait

* feat(map-server): use viewbox search to find visible places

Replace center-point reverse geocoding with Nominatim viewbox search:
- Add searchPlacesInBox() that queries Nominatim with bounded viewbox
- Uses layer=address&featuretype=settlement to find cities/towns
- Returns up to 5 visible places in the current view
- Update model context with 'Visible places: City1, City2, ...'
- Still includes center coordinates and extent dimensions

This provides better context about what's actually visible on the map
rather than just the address at the center point.

* fix(map-server): use CARTO @2x retina tiles for sharp rendering

Root cause: Standard OSM tiles are 256x256 pixels. On Retina displays
(devicePixelRatio=2), these get scaled up 2x, making them look pixelated.

Solution: Switch to CARTO Voyager tiles which provide @2x retina support:
- Detect high-DPI displays using window.devicePixelRatio
- Use 512x512 tiles with @2x suffix on Retina displays
- Use 256x256 tiles on standard displays
- Set tileWidth/tileHeight to match actual tile size
- Use CARTO subdomains (a,b,c,d) for load balancing
- Update CSP to allow CARTO tile domains

CARTO Voyager provides clean OSM-based tiles with free @2x retina support,
no API key required.

* fix(map-server): use OSM tiles and fix reverse geocoding

- Switch back from CARTO to standard OSM tiles (tile.openstreetmap.org)
  for better detail and label rendering
- Fix geocoding: use reverse geocode API instead of search API
  (search API requires a q= parameter, returns 400 without it)
- Update CSP domains for OSM tile server

* fix(map-server): use *.openstreetmap.org wildcard in CSP

Simplify CSP to use wildcard for both tiles and geocoding:
- connectDomains: *.openstreetmap.org covers tile.* and nominatim.*
- resourceDomains: *.openstreetmap.org for tile images

* feat(map-server): multi-point sampling for visible places

- Sample multiple points in visible extent to discover places
- Adaptive sampling based on extent size:
  - < 30km: center only (city zoom)
  - 30-100km: center + 2 corners
  - > 100km: center + 4 quadrants
- Proper rate limiting for Nominatim (1.1s between requests)
- Shows 'Visible places: City1, City2, ...' in model context
- Fix: move geocode tool registration inside createServer()

* format

* fix(map-server): fix Express listen callback + add e2e tests

- Fix incorrect Express listen() callback signature (err param doesn't exist)
- Add map-server to e2e test suite with SLOW_SERVERS timeout (5s for tiles)
- Improve comment about experimental ui/update-model-context API
