fix(copilot): Use correct OpenRouter reasoning API format

Addresses review comments from CodeRabbit and Sentry:

- Change reasoning format from {"enabled": True} (invalid) to
  {"max_tokens": config.thinking_budget_tokens} per OpenRouter docs
- Add missing thinking_budget_tokens config field (default: 10000)
- Extract duplicate code into _apply_thinking_config() helper function
- Update description from 'adaptive' to 'extended' thinking for clarity

- OpenRouter reasoning docs: https://openrouter.ai/docs/reasoning-tokens

-- The SDK built-in Bash tool is NOT available.  Use the `bash_exec` MCP tool
-  for shell commands — it runs in a network-isolated sandbox.
-- **Shared workspace**: The SDK Read/Write tools and `bash_exec` share the
-  same working directory. Files created by one are readable by the other.
-  These files are **ephemeral** — they exist only for the current session.
-- **Persistent storage**: Use `write_workspace_file` / `read_workspace_file`
-  for files that should persist across sessions (stored in cloud storage).
-- Long-running tools (create_agent, edit_agent, etc.) are handled
-  asynchronously.  You will receive an immediate response; the actual result
-  is delivered to the user via a background stream.
