Preserve upstream Node URL and inspect test accounting

Remove nine corpus source rewrites that currently promote upstream test.todo, test.skip, and describe.todo declarations into active tests.

Scope:

• delete rewriteUrlParseQueryCorpus
• delete rewriteNodeUrlCanParseCorpus
• delete rewriteNodeUrlFormatInvalidInputCorpus
• delete rewriteNodeUrlPathToFileUrlCorpus
• delete rewriteNodeUrlFileUrlToPathCorpus
• delete rewriteNodeUrlRevokeObjectUrlCorpus
• delete rewriteNodeUrlNullCharCorpus
• delete rewriteNodeUrlIsUrlCorpus
• delete rewriteNodeInternalInspectCorpus
• route all nine vendored files unchanged and update corpus expectations to preserve their upstream TODO/skip status

Pinned baseline at Bun 4982b91e3 for the combined unchanged set: 6 pass / 3 skip / 7 TODO / 0 fail. Home strict native execution already matches that baseline exactly.

Acceptance:

• fixtures remain byte-for-byte identical to Bun
• no source rewrite activates an upstream-deferred test
• Debug and ReleaseSafe strict/routed counts match pinned Bun
• zero failures and zero unsupported tests
• update #202 and #66 after landing

Completed in 63fbba675.

Deleted all nine scoped rewrite functions and preserved the original upstream test.todo, test.skip, and describe.todo registrations. Updated every duplicated corpus expectation to the exact per-file upstream accounting.

Validation against pinned Bun 4982b91e3:

• pinned Bun combined: 6 pass / 3 skip / 7 TODO / 0 fail
• Home Debug strict: 6 pass / 3 skip / 7 TODO / 0 fail
• Home Debug routed: 6 pass / 10 deferred / 0 fail / 0 unsupported
• Home ReleaseSafe strict: 6 pass / 3 skip / 7 TODO / 0 fail
• Home ReleaseSafe routed: 6 pass / 10 deferred / 0 fail / 0 unsupported
• the reduced routed summary intentionally combines upstream skip and TODO registrations in its TODO counter
• all nine vendored files are byte-for-byte identical to the pinned Bun checkout
• the updated home_test unit executable compiled and linked successfully; its known resource-heavy full-corpus execution was not duplicated after the focused Debug/ReleaseSafe matrices

No fixtures, assertions, timeouts, or runtime behavior were weakened.
