Post-review cleanup: reliability, docs, CI

Reliability / correctness:
- Always arm the graceful-shutdown safety timeout. Previously
  `shutdown(force=true)` (called from uncaughtException) skipped the
  timeout entirely, so a hung `framework.stop()` after a crash would
  wedge the process until Docker's SIGKILL. Now uses 3s when forced,
  8s otherwise, and .unref()s so it never blocks a clean exit.
- Attach a `.catch()` to `framework.start()` so a bad Webex token or
  WebSocket handshake failure produces a clear "Webex framework failed
  to start" error line instead of a bare Unhandled Rejection while the
  bot silently stays dead.
- Rename MDM timestamp labels from "(EDT)" to "(ET)" since the
  formatter uses DST-aware America/New_York (half the year it's EST).

Cleanup:
- Drop `body-parser` in favor of the built-in `express.json()`
  (Express 4.16+). Removes one direct dep; still present as a
  transitive dep of express itself.
- Remove orphaned JSDoc block referring to a helper that no longer
  exists.
- Delete legacy `query-offline.js` (marked deprecated since the bot
  `offline` command shipped) and remove its `APPSPACE_API_TOKEN` /
  `APPSPACE_BASE_URL` env vars from `.env.example` and the
  `offline:legacy` npm script from `package.json`.

Config / metadata:
- Add `"engines": { "node": ">=20" }` to package.json so npm warns on
  the wrong Node version instead of just the README saying so.
- Document `SMOKE_TEST=true` in `.env.example`.

Docs:
- Rewrite README to document the `restart-offline` command (iOS
  Supervised requirement, 50-device cap, concurrency, audit log
  fields, fresh-at-execute semantics), the ET-not-EDT labeling,
  structured error logging, character-budget rendering, and the
  new CI workflow. Refresh the TODO section to reflect what has
  actually shipped.

CI:
- Add `.gitea/workflows/ci.yml` with two jobs: syntax check
  (`node --check` on index.js and mdm.js) and a Docker smoke test
  that builds the production image, boots it with dummy credentials
  + SMOKE_TEST=true, and waits up to 30s for the container's
  built-in healthcheck to reach `healthy`. Dumps container logs
  on failure.

+## Bot Commands
+
+In the Webex space where the bot is added — either as a DM to the bot, or `@mention` in a group space:
+
+| Command | What it does |
+| --- | --- |
+| `offline` | Snapshot of all currently offline / lost / failed Appspace devices, grouped by location, enriched with per-device MDM facts and clickable Appspace + Workspace ONE console links. |
+| `offline <filter>` | Same, narrowed to devices whose `deviceType` or name contains the filter substring. E.g. `offline ios`, `offline lobby`. |
+| `restart-offline` | Sends a Workspace ONE **SoftReset** (reboot) to every currently-offline device that maps to a WS1 record by serial. Capped at **50** devices per invocation. Skipped devices (no WS1 record) are reported separately. |
+| `restart-offline <filter>` | Same, narrowed to devices matching the filter. Use this to get under the 50-device cap for large fleets (e.g. `restart-offline ios`). |
+| `help` | Print the command list. |
+
+Notes on `restart-offline`:
+
+- **Fresh at execute time.** The command re-queries Appspace at the moment of execution, so devices that came back online after you last looked are automatically excluded.
+- **No confirmation prompt.** Configured for immediate execution per project preference — narrow with a filter if you want to limit scope.
+- **iOS Supervised requirement.** WS1's SoftReset only actually reboots iOS devices that are Supervised (DEP-enrolled). Non-Supervised devices will surface a clean WS1 error in the failure list; they will not silently appear to succeed.
+- **Rate-limited.** Reboots are sent with concurrency = 3 to avoid hammering the WS1 API.
+- **Auditable.** Every invocation emits a JSON log line with `user`, `filter`, `matched`, `withMdm`, `withoutMdm`, `succeeded`, and `failed` counts.
+
+The bot runs in WebSocket mode (no public webhook required).

-- Appspace token uses refresh token + cooldown + safety buffer.
+- Appspace token uses refresh-token flow with cooldown, safety buffer, and in-flight promise coalescing so burst traffic doesn't stampede the token endpoint.

+- WebSocket mode for the bot avoids the WebSocket-restart rate limits associated with the webhook mode.
 - All enrichment is best-effort; alerts are never blocked by MDM or token issues.
+- Webex message rendering respects the 7439-character pre-encryption limit by building bodies incrementally against a character budget, with accurate "N more not shown" truncation notes.
+- Bot command matching uses string phrases so the framework's `(^| )phrase($| )` wrapper handles group-space `@mentions` correctly. Filter parsing works identically in DMs and mentioned messages via a shared helper.
