Slack:
- Add Block Kit interactive buttons for command approval (Allow Once,
Allow Session, Always Allow, Deny) via send_exec_approval()
- Register @app.action handlers for each approval button
- Add _fetch_thread_context() — fetches thread history via
conversations.replies when bot is first @mentioned mid-thread
- Fix _has_active_session_for_thread() to use build_session_key()
instead of manual key construction (fixes session key mismatch bug
where thread_sessions_per_user flag was ignored, ref PR #5833)
Telegram:
- Add InlineKeyboard approval buttons via send_exec_approval()
- Add ea:* callback handling in _handle_callback_query()
- Uses monotonic counter + _approval_state dict to map button clicks
back to session keys (avoids 64-byte callback_data limit)
Both platforms now auto-detected by the gateway runner's
_approval_notify_sync() — any adapter with send_exec_approval() on
its class gets button-based approval instead of text fallback.
Inspired by community PRs #3898 (LevSky22), #2953 (ygd58), #5833
(heathley). Implemented fresh on current main.
Tests: 24 new tests covering button rendering, action handling,
thread context fetching, session key fix, double-click prevention.
