chore(sync): cascade ignore-block + repo lint cleanup

Cascade adds fleet-canonical-begin/end block to .config/oxlintrc.json
and .config/oxfmtrc.json so downstream skips wheelhouse-owned files.
Also resolves 28 pre-existing lint errors blocking commits: removes
TODO placeholders, reorders top-level exports alphabetically, swaps
fetch() for httpRequest, flips null to undefined, ignores local
transpiled .mjs output, and adds disable comments where stat metadata
is genuinely required.
