* perf(auto_resource): reuse historical ownership lookup per batch
Share a lazy ownership index across routed processors and expire it at the end of each resource batch. Refresh changed days and their safe aliases after writes, deletes, and partial failures.
Add regression coverage for scan counts, ownership, lookup scope isolation, and retry behavior.
* fix(auto_resource): reconcile shared lookup across active batches
* fix(auto_resource): refresh batch ownership from filesystem metadata
* refactor(auto_resource): simplify batch ownership lookup
Keep per-day ownership caches paired with pre-read metadata and refresh changed days before subsequent resources. Remove reverse-index bookkeeping, post-read stabilization retries, and recursive scope fallback.
Handle late ELOOP errors on Python 3.13 while preserving other OS errors. Update regression tests for cross-resource freshness and retain safety and lifecycle coverage.
* refactor(auto_resource): streamline batch lookup refresh
* refactor(auto_resource): scope ownership cache to batch mutations
Replace filesystem snapshots with one lazy historical lookup shared by resource processors. Reload only days changed by this invocation and discard the cache when it ends.
Reuse canonical daily-note scans for symlink safety and Python 3.13 compatibility. Consolidate regression tests around the narrowed batch contract.
Validation: Python 3.11, 3.12 and 3.13 core/plugin suites each passed 1407 tests; pre-commit --all-files and offline lookup/deletion comparison passed.
* refactor(auto_resource): reuse initial ownership without refreshes
* test(auto_resource): streamline ownership lookup regression coverage
