web: Group tool-result resource_links in a scrollable "Resource Links" box with Protocol colors (#1686)

* web: Group tool-result resource_links in a scrollable "Resource Links" box with Protocol colors

Closes #1685

- ToolResultPanel: coalesce consecutive `resource_link` blocks into a
  single bordered, internally-scrollable "Resource Links" box (mirroring
  the "Messages" box in the Protocol monitoring sidebar). Non-link blocks
  and non-adjacent runs are preserved in order via `segmentContent`.
- ResourceLink: render each link card on the recessed `inset` surface
  (`Card variant="inset"`), matching ProtocolEntry's colors in light and
  dark modes; nested read-result Code blocks read as raised on the grey
  card via the inset cascade variable.
- Drop redundant metadata: the resource `description` line
  (ResourceLinkInfo, and thus ContentViewer/ResourceLink) and the green
  "Resource:" label above the expanded read result.
- Update tests + stories for the removed props/label and the new grouping
  box; add multi-link and split-run coverage.

* web: keep the resource_link description; only drop the "Resource:" label

Reverts the description removal from the previous commit per review — the
`description` line is retained on ResourceLinkInfo (and its ContentViewer /
ResourceLink callers). Only the redundant green "Resource:" label above the
expanded read result stays removed.

* web: drop the resource_link description from the link cards

The `description` is generated by the server and can be misleading — e.g. a
blob resource served with a `text/plain` mimeType gets described as a
"plaintext resource" even though the payload is a blob. Rather than surface
that nonsense text, drop the description line from ResourceLinkInfo (and its
ContentViewer / ResourceLink callers) entirely.

Reverts the description-retention from the prior commit; the grouped
"Resource Links" box and the "Resource:" label removal are unaffected.

* web: refine resource-link cards — URI-below-name + copy, ProtocolEntry toggle, full-height box

Follow-up refinements to the Resource Links display:

- ResourceLinkInfo: move the URI below the name and add a CopyButton beside
  it so the URI can be copied. The name + MIME badge (and the optional
  expand control) sit on the header row; the URI + copy sit on the row below.
- ResourceLink: replace the bespoke chevron with the same tooltip'd
  ExpandToggle used by ProtocolEntry, and animate the read-result panel with
  Mantine's Collapse (same as ProtocolEntry). The toggle is a sibling of the
  URI copy button (no card-wide wrapping button) so the two real buttons
  never nest (axe `nested-interactive`).
- ToolResultPanel: when a result contains a Resource Links box, fill the
  card's height so the box grows into the available space and scrolls
  internally (pinned "Resource Links" heading), instead of capping at a fixed
  content height. Plain text/image results keep the scroll-within-card body.
- ToolsScreen: give the result card `flex: 1` so it fills the pane, providing
  the definite height the Resource Links box grows into.
- Tests/stories updated for the new layout, the Expand/Collapse toggle labels,
  the mounted-through-collapse read result, and the full-height box (with a
  height-bounded decorator on the ResourceLinks story).

* web: align resource-link card with ProtocolEntry — toggle row, badge, URI style

Bring ResourceLinkInfo closer to the ProtocolEntry message card:

- Move the expand/collapse toggle to the second (URI) row, opposite the copy
  button — mirroring ProtocolEntry, whose toggle sits on the row below the
  badges. The MIME badge stays on the header row's right, beside the name.
- MIME badge: bump to `size="md"` so the lowercase MIME text matches the point
  size of ProtocolEntry's uppercase method/status badges, and make it a solid
  dark-blue fill with white text in dark mode (keeping the blue-light tint in
  light mode) instead of a washed-out translucent chip.
- Render the URI like ProtocolEntry/NetworkEntry render URLs — `sm` / `fw: 500`
  in the default sans-serif face and text color — rather than a blue monospace
  "link". `monoBreak` is kept only for long-URI wrapping.

* web: scope result-card fill to resource-link results (review follow-up)

Code-review finding: ToolsScreen gave the result card `flex={1}`
unconditionally, so plain text/image/error results also filled the full pane
height — leaving a tall empty card and a height jump versus the input-form
state. Fill is only needed so a "Resource Links" box can grow and scroll.

Gate the fill on a new `resultHasResourceLinks(result)` helper (extracted to
`toolResultUtils.ts` so the component module keeps exporting only components,
per react-refresh/only-export-components). Non-link results keep their
content-sized card; link results still fill and scroll internally.

Tests: unit tests for the helper (link / text-only / empty / error) and a
ToolsScreen test that a resource-link result renders the Resource Links box
(covering the `flex={1}` branch).

* web: prettier-format the resultHasResourceLinks error-case test fixture

The error-case fixture in ToolResultPanel.test.tsx wasn't re-formatted after
adding the required `name` field, failing CI's `format:check`. No logic change.

* web: cap a non-link block above the Resource Links box at 50% height

Addresses the mixed-content case from the review: a long text block preceding
the links would take its full natural height and push the Resource Links box
almost entirely off-screen (only the first card peeking at the bottom).

In the links-containing result, wrap each non-link block in a ScrollArea.Autosize
capped at `mah: 50%` (flex "0 1 auto"), so it scrolls within at most half the
card and the links box keeps the rest. A short block still takes only its
content height; a result with no links renders non-link blocks uncapped in the
outer scroll body as before.

Adds a `ResourceLinksWithLongText` story (full-height decorator) exercising the
cap. Verified visually: the text scrolls within ~50% and the links box fills
the remainder.

* web: address review — expand-toggle a11y, stale JSDoc, stronger fill test

Review follow-ups on PR #1686:

- ExpandToggle: add an optional `ariaLabel` (defaults to the tooltip verb, so
  ProtocolEntry/NetworkEntry/Task are unchanged) and expose `aria-expanded`.
  ResourceLink passes a per-resource label ("Expand/Collapse resource <uri>")
  so multiple link toggles are distinguishable to assistive tech and announce
  their state — restoring the a11y the card-wide button previously provided,
  while keeping the visible tooltip a plain "Expand"/"Collapse".
- ResourceLinkInfo: fix the stale JSDoc that still described the URI as
  "monospace, link-styled" — it now renders sans-serif sm/fw:500 default color.
- ToolsScreen test: assert the result card actually gets `flex: 1` for a
  links result and NOT for a plain text result, so the test verifies the fill
  branch it names rather than only that the heading renders.

Tests: ExpandToggle gains ariaLabel + aria-expanded cases; ResourceLink /
ToolResultPanel / stories updated for the per-resource toggle name.

* web: restore cli/tui/launcher package-locks accidentally committed

These lock files were touched by a local install in the worktree (dropping the
`version` field and adding optional @emnapi platform deps); they are unrelated
to this PR. Restore them to their v2/main state.
