test: type runtime test filters

[kojiwakayama]

Summary

• Adds a JSDoc contract to filterTestFiles so TypeScript callers see include and exclude as string[] filters.
• Fixes the standalone deno check tests/runtime-test-filters.test.ts diagnostic that PR fix(server): restrict project chooser to trusted loopback requests #3743 missed because it merged before the type-only helper commit landed.
• Preserves runtime behavior; this is a JSDoc-only follow-up.

Verification

• Red before fix: Deno 2.7.7 deno check tests/runtime-test-filters.test.ts failed at tests/runtime-test-filters.test.ts:39:53 and :45:52 with string[] not assignable to never[].
• Green after fix: Deno 2.7.7 deno check tests/runtime-test-filters.test.ts.
• Green after fix: pinned Deno focused runtime filter test, 1 passed (4 steps), 0 failed.
• Green after fix: pinned Deno deno task fmt:check, deno task lint:ci, deno task typecheck.
• Full pre-push: first run exposed unrelated timing failures in src/agent/runtime/project-files-client.test.ts and src/react/compat/ssr-adapter/stream-renderer.test.ts; both exact files passed on direct rerun. Second full .husky/pre-push run passed with All pre-push checks passed!.

Final readiness

• Exact head: d23d0694eaf58693bc5a502dde3ac087c2e8e4c8.
• Exact-head GitHub CI is green with no pending or failed checks.
• Review threads: 0 unresolved.
• Fresh independent Standards and Spec reviews both approved at 98% confidence.
• Aggregate merge confidence: 98%.
