Fix Tag rules : tag/.* does not include tag

[Shivajith754]

Fixes #6188
Added hierarchy-aware matching for rules ending in /.* by testing the tag with an empty slash suffix, while preserving the existing anchored regex behavior for all other rules and exact-key precedence.

Walkthrough

Updated tag rule matching to support trailing /.* patterns for both the hierarchy prefix and its descendants. Exact patterns continue to match only the exact tag. Regex-based metadata lookup now uses the shared matching helper. Added tests for prefix inclusion, descendant matching, similarly prefixed tag exclusion, and exact-pattern behavior.

Merge Risk: ⚪ Minimal · up to 8523b

The tag-rule matching change is localized to hierarchy handling and its tests; no actionable merge-blocking risk remains at the current head, so it is merge-ready after normal checks.

Greptile Summary

This PR makes hierarchy rules ending in /.* apply to the hierarchy’s parent tag as well as its descendants while preserving exact-key precedence and anchored matching for other rules.

• Adds an empty-suffix hierarchy check to tag metadata matching.
• Adds tests covering parent, descendant, non-prefix, and ordinary exact-pattern behavior.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking issue identified.

The new fallback is limited to patterns ending in /.*, retains anchored regex behavior, and the tests cover the intended parent and descendant cases without exposing a concrete regression.

Important Files Changed

Filename	Overview
web/src/lib/tag.ts	Adds a focused helper that extends trailing /.* rules to hierarchy parent tags without changing exact-key precedence.
web/tests/tag.test.ts	Adds regression coverage for hierarchy-parent matching and unchanged exact-pattern behavior.

Add a regression test for exact-key precedence.

When both tagA and tagA/.* exist, verify that findTagMetadata("tagA", setting) returns the metadata for the exact tagA key. Also verify that tagA/child returns the hierarchy-rule metadata.
