Diego Rodrigues de Sa e Souza 0bb17b91c6 maint: final follow-up cherry-pick #9812 (#9907)
* fix(deps): bump transitive deps for 6 Dependabot + remaining audit vulns on main

Same overrides as #9464 (ip-address, hono, fast-uri, socket.io-parser, undici)
applied directly to main. Also covers brace-expansion (scoped), js-yaml v4 copies,
and mermaid.

npm audit: 6→0 vulnerabilities.
Closes Dependabot #161-#166.

* fix(deps): bump nanoid, dompurify for 2 new Dependabot alerts (#189, #190)

Bumps: nanoid ^3.3.17 (was transitive, now overridden), dompurify ^3.4.13
(with monaco-editor scoped override). Closes Dependabot #189, #190.

Remaining #182-#188 (js-yaml + mermaid) already closed by #9651 merge —
awaiting Dependabot re-scan.

npm audit → 0 vulnerabilities.

* fix(repo): harden .gitignore to also ignore a _tasks symlink (/_tasks)

_tasks is a SEPARATE nested git repo (gitignored). The pattern _tasks/ (trailing
slash) ignores only a directory, not a SYMLINK named _tasks. A self-referential
_tasks symlink can slip in via git add -A and, once pulled, checkout materializes
it over the real _tasks repo (destroying plans/specs/hands-off). Anchored /_tasks
ignores the symlink too, preventing re-capture.

* feat(telegram): Mini App chat bridge — initData auth, update webhook, chat proxy

Implements the Phase-1 slice of the Telegram Mini App integration
(docs/proposals/TELEGRAM-MINIAPP.md):

- src/lib/telegram/initData.ts — dependency-free WebApp initData HMAC-SHA256
  verification (Telegram Bot API spec), with auth_date freshness check.
- src/lib/telegram/config.ts — TELEGRAM_BOT_TOKEN / model / API base / timeout
  env config; token format validation; enabled gate.
- src/lib/telegram/botApi.ts — minimal fetch-based Bot API client
  (sendMessage, editMessageText, setWebhook) + update shape helpers.
- src/lib/telegram/chatProxy.ts — maps a Telegram user to a per-user
  OmniRoute API key (createApiKey, name telegram:<userId>) and proxies
  prompts through the existing handleChat pipeline.
- src/app/api/telegram/update/route.ts — inbound endpoint serving both the
  Bot API update webhook (/start + chat replies) and the Mini App direct
  path (initData HMAC verified → 401 on mismatch). Public route prefix;
  own auth only.
- src/app/miniapp/page.tsx — Telegram WebApp SDK chat UI.
- Tests: telegram-init-data (7), telegram-botapi (5) — 12/12 pass.
- Env docs: TELEGRAM_* vars in .env.example + ENVIRONMENT.md (sync ✓).
- Route-validation check: PASS (body validated via Zod).
