Add Telegram notifications plugin (noobitoo.telegram-notifications)

[NooBiToo]

Adds a community notifications plugin to the marketplace index.

Plugin

• id: noobitoo.telegram-notifications
• source: https://github.com/NooBiToo/orca-telegram-notifications.git @ v0.4.1
• categories: ["notifications"] (community; no official)
• requires: Orca >=1.4.0, pluginApi 1

What it does

Sends a Telegram message when an agent changes status (finished, needs attention, stuck, error, waiting — user-configured keyword filter, optional workspace filter, anti-spam quiet window persisted across worker restarts).

• Worker (main.mjs, plain Node) subscribes to agent.status.changed and posts via the Telegram Bot API. Messages use human titles per status (✅ finished / 🙋 needs attention / ⚠️ stuck …), Telegram HTML format, optional custom template with {{title}} {{worktree}} {{state}} {{time}} placeholders.
• Panel — a setup guide; the actual settings UI is a localhost page the worker starts on demand (command Telegram: Open settings page), since panels are sandboxed documents and cannot hold secrets by design.
• Config lives outside the immutable install tree (~/.orca-plugin-config/telegram-notifications.json) so user edits never trip the host's content-hash integrity check.
• Capabilities requested: storage, secrets, settings:own, events:subscribe, notifications:show — no terminal, no workspace access.

Validation

• Manifest and catalog verified against the host loaders shipped in v1.4.191/v1.4.192 (parsePluginManifest schema rules and parsePluginLanguagePackArtifact discipline applied to config handling); install from git URL with #ref verified end-to-end on Orca 1.4.191/1.4.192 (Windows): install → review → enable → command palette → settings page → Telegram delivery.
• 27 local assertions around status filtering, workspace filtering, anti-spam persistence, and message building run in-repo (node scripts/test-local.mjs).

What's new in v0.4.1

• Project / workspace shown with human names from the Orca store (profiles/<profile>/orca-data.json): project line + workspace title (git worktrees use their Orca displayName, folder workspaces their name, e.g. gittracker / #GT-89); falls back to the path basename if the store is unavailable.

What's new in v0.4.0

• Notification format: project name + workspace name (parsed from worktreeId) instead of the raw uuid::path, localized status words, the noisy pane line removed.
• The agent's last message (from the Stop hook, persisted by the host in agent-hooks/last-status.json) is appended to the notification (💬, truncated to 700 chars) — the plugin worker reads it directly from disk since the plugin event payload strips this field. Degrades gracefully: no file/field → no 💬 line.
• Message labels now respect the configured language (RU/EN).

Note

This is the second plugin from the same author as #3 (Russian language pack); PRs are independent and can be reviewed/merged separately.
