P4-T1: Auto-restart stale broker daemon on version mismatch after upgrade

[SoundBlaster]

Description

Implements P4-T1 end-to-end with FLOW artifacts and runtime changes for broker version lifecycle safety.

Key changes:

• Derive package version from importlib.metadata in mcpbridge_wrapper.__init__.
• Add broker version stamp support (broker.version) via BrokerConfig, daemon write/cleanup, and daemon status payload.
• Add proxy stale-daemon handling for version mismatch (_check_version_mismatch, _stop_stale_daemon, file cleanup).
• Add CLI lifecycle commands: --broker-status and --broker-stop.
• Stop running broker daemon in scripts/install.sh and scripts/uninstall.sh before file operations.
• Update docs/broker-mode.md for status/stop/version-management guidance.
• Add/expand tests (including new tests/unit/test_init.py) and archive task/review artifacts.

Validation run:

• pytest → 766 passed, 5 skipped
• ruff check src/ → pass
• mypy src/mcpbridge_wrapper → pass
• pytest --cov=src/mcpbridge_wrapper --cov-report=term-missing → 90.71%
