Absorb fork fixes and features; release 0.15.53

Adapted from community forks (ardhiqii, kkunkunya, nihar-oracle, steimerbyte):

- Abort stalled /next long polls after 45s; time out, retry, and single-post results.
- Fall back to CDP Runtime.evaluate when chrome.scripting is refused (about:blank automation tabs).
- Load pi-chrome in same-process subagent sessions as a bridge client; client chrome_launch reports owner status.
- Add chrome_cdp (validated raw CDP passthrough, background-guarded, payload summarization) and chrome_cdp_targets.
- chrome_type reports before/after values, insertedAt, splice/unchanged warnings; add replace=true.
- includeSnapshot waits for navigations started by the action; tab.new reports the settled tab.
- CDP timeouts surface as timeouts and are not re-sent after the cleanup detach.
- Activate/deactivate chrome_find and chrome_inspect with the rest of the chrome_* tools.
- New unit suites: bridge-resilience, cdp-passthrough, type-evidence.
