What's Changed
Fixes
Fixed history deletion edge cases for redirected/canonical URLs.
Handles http/https, www/non-www, and trailing-slash variants more reliably.
Fixed Forget current page to remove the current page and its sub-pages (descendant paths), not just the exact URL.
Fixed periodic sweep behavior so an alarm only applies the rule that scheduled it (prevents unrelated rules from piggybacking on the same sweep).
Fixed action result handling so partial history deletions are treated as failures (improves retry/buffering correctness).

Improvements
Improved background-task reliability by catching/logging errors from detached async work (startup, alarms, navigation-triggered deletion, rule reloads).
Improved per-entry history deletion logs with trigger context (for example: asap, tabClose, browserClose, manualForget, periodic, bufferRetry).
Improved deletion engine robustness by parsing hostnames lazily (cache-only actions no longer fail just because a hostname can’t be parsed).
Reduced repeated URL parsing in history matching for better maintainability/perf.
