submanifest bench: report the real optimize mode, not a literal

The emitted `optimize` field was the string "ReleaseFast", hardcoded into the JSON format string rather than derived from anything. It reported ReleaseFast for every record the benchmark has ever written, whatever the executable was actually built as - so the one field whose job is to say which binary produced a measurement could not be wrong in a detectable way, only in a silent one.

Now `@tagName(builtin.mode)`, alongside the os/arch tags beside it that were already derived that way.

Found by switching bench to ReleaseSafe and watching `executable_sha256` change while `optimize` did not. check-in: be18ff3902 user: dmestas tags: sub-manifest

Sub-manifest: card alphabet, artifact type, and the specification's vectors

Adds S as the twenty-second card letter and SUBMANIFEST as the ninth artifact type, per draft-fossil-submanifests-00 sections 3 and 4. Type determination reassigns after the card scan rather than during it, so no type is committed while cards are still being read (section 9.1). Reading and classification only: no tree walk, no emission.

The draft's seven appendix vectors ship alongside, each named by the SHA3-256 the draft states and checked by a test that recomputes it. check-in: 9b8bad477a user: dmestas tags: sub-manifest
