Feature request: Video recording support

[luisrudge]

Summary

Add support for recording browser sessions to video files (e.g., .webm), similar to Playwright's built-in video recording.

Use Case

• PR demos: Record a feature flow to attach as a GIF/video in pull requests
• Bug documentation: Capture reproduction steps visually
• Test artifacts: Save recordings of failed E2E tests for debugging

Proposed API

# Start browser with recording enabled
agent-browser open example.com --record

# Or enable per-session
agent-browser --session demo --record open example.com

# Videos saved on close
agent-browser close
# Output: Video saved to ./videos/session-demo-1234567890.webm

Alternatively, explicit start/stop:

agent-browser record start [path]
agent-browser record stop

Prior Art

• Playwright's recordVideo option in browser context
• dev-browser skill's --record flag which saves .webm files per page

Notes

Since agent-browser already uses Playwright under the hood, this should be straightforward to implement via recordVideo in the context options.

video recording now available via #116

not yet tagged in new release but just tried it by building from source and it works

This is already supported in the current codebase:

agent-browser record start demo.webm
# ... do actions ...
agent-browser record stop

See also PR #450 which includes additional recording improvements. This issue can likely be closed.
