* test(#1074): add additive per-file workflow size baseline guard (PR 1/3)
Introduces a committed per-file size baseline scheme alongside (not replacing)
the existing tier anti-creep tests. Green by construction — the baseline
records current sizes, so both schemes pass side by side during migration.
- scripts/lib/allowlist-ratchet.cjs: add assertFileBaseline (third pure helper,
same injected-fail style) — per-file growth/shrink/add/remove diff vs baseline.
- scripts/workflow-size.cjs: single source of truth for LF-normalized byte
counting (#683) + workflow enumeration, shared by the guard and the generator
so they can never measure differently. Lives in scripts/ root (NOT scripts/lib/)
because it is dev/CI-only tooling — scripts/lib/ is bundled into the installed
runtime, scripts/ root is not, so this keeps it out of the shipped payload.
- scripts/update-size-baseline.cjs + npm run size:baseline: regenerate the
snapshot (sorted keys, trailing newline, idempotent).
- tests/workflow-size-baseline.json: generated snapshot (88 workflows).
- tests/workflow-size-budget.test.cjs: import the shared counter (drops the
duplicated local byteCount) and add the per-file baseline describe block.
- Tests for the helper, the shared module, and the generator (incl. round-trip
and fault-injection cases).

* test(#1074): regenerate workflow baseline after Update-branch merge with next
The 'Update branch' merge (652a916b) pulled in next's update.md change (#1090)
without regenerating the snapshot, leaving the per-file baseline stale by one
file. Re-ran `npm run size:baseline` so the committed baseline matches the
merged workflow files.
Refs #1074.
