fix(library): ignore sentence punctuation after bare internal URLs in check:library-content

[waleedlatif1]

Summary

• check:library-content read a bare internal URL that ends a sentence (…see https://www.sim.ai/library/<slug>.) as the slug <slug>. and reported a valid link as missing
• Strip trailing sentence punctuation (.,;:!) from the captured slug before the lookup; route segments with a dot such as rss.xml are unaffected
• Raised on v0.9.10: geo, chat fixes, sandbox fixes #8539

Type of Change

• Bug fix

Testing

• scripts/check-library-content.test.ts: added a passing sentence-ending bare URL to the clean-post case and a sentence-ending broken URL to the missing-link case (reported as /library/<slug>, not <slug>.); both fail without the fix, 19/19 pass with it
• bun run check:library-content (80 posts), bun run lint, bun run check:audits (54 passing), docs-manifest:check

Checklist

• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)

• scripts/check-library-content.ts can treat escaped Markdown prose as a library link and include its trailing period in the slug, leading to incorrect audit results. Ignore escaped openers and strip trailing punctuation from actual link targets.

P2: Distinguish escaped Markdown openers from actual link targets here; `\[label](https://www.sim.ai/library/kept-guide.` is prose, but this treats it as an explicit target and leaves the period in the slug, so the audit still fails.</violation>
