Closes #507.

Problem

With the sample GitHub Issues rule (REGEX detection github\.com/.+/issues/\d+, URL matcher github\.com/.+/issues/(\d+)), turning on Unique closes every other issue, not just other tabs of the same issue.

The unique key was the processed url_fragment, which only varies when the fragment holds $n placeholders. But a fragment with $1 never matches during detection (see the analysis in #507). So for any rule that actually matches, every tab got the same key.

Fix

New _getUniqueKey(urlFragment, url, urlMatcher) in helpers.ts, used for both the duplicate comparison and the per-group lock from #558:

Rule	Unique key	Effect
no url_matcher	url_fragment	unchanged: one tab per rule
url_fragment with $n	processed fragment	unchanged
url_matcher with capture groups	the captured values	new: one tab per issue number, ticket id…
url_matcher without capture groups, or no match	url_fragment	unchanged

This replaces the unique_pattern proposal with no new field and no UI change; docs/unique-pattern-proposal.md is marked as superseded. The URL matcher help text in the rule form explains it.

Behaviour change

Rules that combine Unique with a url_matcher that has capture groups now close fewer tabs: only those with the same captured values, never more. This is what the sample GitHub Issues rule implies, and what the reporter expected.

Tests

• _getUniqueKey: capture groups, $n fragment, no matcher, no capture group, no match, invalid regex.
• End to end with the sample GitHub rule: another tab of the same issue (#issuecomment anchor) is closed; issues 123 / 456 / 789 all stay open. Both fail on master.
• 234 tests, ESLint, Prettier, vue-tsc and build pass.
