feat: add video recording tools for browser sessions

Add three new MCP tools for recording browser automation:
- browser_start_recording: Enable video recording with configurable size/filename
- browser_stop_recording: Stop recording and return video file paths
- browser_recording_status: Check recording status and configuration

Key features:
- Automatic video saving when pages/contexts close
- Configurable video size and output directory
- Enhanced LLM guidance with clear workflow instructions
- Integration with existing browser context management

Videos are saved as .webm files in {outputDir}/videos/ directory.
