[vycdev2]

Summary

• Fix tag cleanup and hidden-tag labels after a backtick with no matching closer. The unmatched backtick is literal text, not an inline code span.
• Reuse the existing inline-code mask, preserving tags in complete spans. Add regression coverage and a changelog entry.

Verification

• ./node_modules/.bin/mocha -r ts-node/register test/tags.spec.ts --exit — regression failed before the fix (the repository's Mocha configuration also ran other specs).
• npm test — passed, 416 tests.
• npm run typecheck — passed.
• npm run compile — passed.
• npm run format:check — passed.
• git diff --check upstream/develop...HEAD — passed.

Risk

• Low: tag removal now uses the already-shared inline-code masking semantics; existing complete-span tests still pass.
