Fix catalog book links and rewrite PDF destinations to live HTTPS.

Module and model book cards now point at generated index.html/index.pdf
instead of directory URLs that 404. WeasyPrint file:// annotations are
mapped to https://zapier.georgelambert.org/ paths that exist. Developer
module, architecture, and research snapshot links target published files.

+# Restart Grok for this Zapier workspace
+
+## 1. Leave the TUI
+
+In Grok type:
+
+```
+/quit
+```
+
+(` /exit ` is the same.) Do **not** use `/new` — that throws away this session.
+
+## 2. Run the restart script from a normal shell
+
+```bash
+cd /Users/marchon/research/zapier
+./scripts/restart-grok.sh
+```
+
+That script:
+
+1. `cd`s to this repo
+2. Puts `zapier-platform` / `zapier-sdk` on `PATH`
+3. Loads `~/.mcp-env` (Mongo URI)
+4. Starts `scripts/mongo-tunnel.sh` if `127.0.0.1:27017` is down
+5. Runs `grok --resume` (latest session for this directory)
+
+## 3. After Grok opens
+
+```
+/mcps
+```
+
+Press `r` to refresh. Confirm **mongodb** is connected.
+
+Then continue:
+
+```
+/zapier-build
+```
+
+or ask Grok to load:
+
+```js
+db.platform_reference.findOne({ kind: "guide", key: "build-new-connector" })
+```
+
+## Other scripts
+
+| Script | What it does |
+|--------|----------------|
+| `scripts/restart-grok.sh` | Tunnel + `grok --resume` |
+| `scripts/ensure-mongo-tunnel.sh` | Start tunnel only |
+| `scripts/mongo-tunnel.sh` | Raw `ssh -N -L 27017:… ns1` (foreground) |
+| `scripts/dev-env.sh` | `source` this for PATH + Mongo URI |
+| `scripts/zapier-status.sh` | Check tunnel, CLIs, login, Mongo count |
+
+```bash
+./scripts/zapier-status.sh
+```
