v0.9.9 Maintenance Release

This maintenance release hardens cross-platform browser lifecycle handling and asynchronous query polling.

Fixed

Windows CDP handoff now validates that a late listener belongs to the requested profile before accepting it.
Home-directory resolution now survives constrained environments and honors the configured storage path for browser and Snap discovery.
WSL browser startup preserves non-ASCII Windows temporary-profile paths through explicit UTF-8 subprocess handling.
Completed and failed asynchronous query results remain available until their configured TTL.
Externally managed local CDP browsers are closed only when profile ownership is verified, with replacement listeners protected from accidental cleanup.

Thanks to @insane66613 for PRs #288, #289, and #290.
Thanks to @etadward and @Joystick01 for the detailed issue reports behind the WSL and async-query fixes.

Focused regression tests pass for CDP ownership, home resolution, WSL encoding, Snap routing, and query retention.
Full non-live suite passes: 1,402 passed, 38 skipped, and 1 live upload test deselected. Ruff lint, formatting, and package build pass.
