- Rename timezone_id → timezone in launch_context(), launch_persistent_context(),
and launch_persistent_context_async() (Python)
- Extract _migrate_timezone_id() helper for deprecation compat (DRY)
- Always pop timezone_id from kwargs to prevent override via context_kwargs.update()
- Use FutureWarning (visible by default) instead of DeprecationWarning
- JS: deprecate timezoneId on LaunchContextOptions with runtime shim
- Extract migrateTimezoneId<T>() shared helper in playwright.ts (DRY)
- Bump version to 0.3.7 in _version.py and package.json
- Add 4 Python + 4 JS unit tests for deprecation compat behavior
launch() and launch_context() now inject --timezone and --lang binary
flags when timezone/locale params are set. Previously only the Playwright
context layer was configured, leaving a detectable mismatch that CreepJS
flagged as a bot signal.
