feat(telegram): add progress_updates and show_typing configuration settings

Description

This PR introduces new configuration options to the TelegramTransport to allow finer control over user feedback during long-running operations. Currently, the transport defaults to streaming full progress updates, which can be noisy in certain contexts.

Key Changes

1. Added progress_updates setting:

   • Controls the frequency of progress messages sent to the user.
   • Options:
     • "full" (default): retains existing behavior (streaming updates).
     • "once": sends an initial "working" message but suppresses subsequent intermediate updates until completion.
     • "none": suppresses all progress messages; only the final result is sent.

2. Added show_typing setting:

   • Type: bool (default: False).
   • When enabled, the bot sends a continuous "typing" action to the chat while processing, providing a subtle visual cue to the user without decluttering the chat history with messages.

3. Implementation:

   • Updated TelegramTransportSettings in src/takopi/settings.py.
   • Extended BotClient protocol and implementations (HttpBotClient, TelegramClient) to support send_chat_action.
   • Modified ProgressEdits logic in src/takopi/runner_bridge.py to respect the new settings.
   • Added a background loop to maintain the "typing" status if enabled.

4. Fixes:

   • Improved takopi.__init__ version retrieval to gracefully handle cases where the package is not installed (e.g., during local development), preventing PackageNotFoundError.

Verification

• Added unit tests in tests/test_settings_custom.py to verify configuration loading and defaults.
• Added unit tests in tests/test_runner_bridge_progress.py to verify the logic for all three progress_updates modes and the show_typing behavior.
• Ran full test suite to ensure no regressions.

---

Checklist

• Tests passed.
• Code style and linting checked.
• Backward compatibility maintained (defaults match previous behavior).
