ldm0 abc7de49fa perf(browser): reduce navigation owner round trips
Return the superseded navigation and original decision permit with the existing
admission receipt. Read the current Document URL and the controller's retained
navigation IDs together instead of issuing separate synchronous owner queries.
Keep the controller's retention rule and the owner's stale-permit validation.

Add a native admission/supersession regression and record the command-stage
measurements. Ordinary navigation admissions now use 10 owner calls instead of
14, reducing median command latency by 6.6–18.3% in three matched rounds while
remaining 0.24–0.39 ms behind pinned main.

Validation: root fmt, strict workspace Clippy, 1,443 adjacent tests and all
19,497 default-profile tests pass (13 configured skips, zero retries). CDP,
WebDriver and shared-page probes pass. Retain the Network burst capacity
failure: both parent and candidate close 4/10 bounded runs, with diagnostics
reaching the existing 1,536-observation transport limit. No capacity change or
claim of full Network burst acceptance is included.
