regen(surface): the two committed artifacts the SWAIG regen staled

SIGNATURES-FRESH and DOC-SURFACE-FRESH both compare a fresh enumeration against
`git show HEAD:<artifact>`, so the preceding SWAIG regen staled both the moment
it landed. Regenerated with the port's own enumerators, nothing else touched:

  npx tsx scripts/enumerate-signatures.ts  --out    port_signatures.json
  npx tsx scripts/enumerate-doc-surface.ts --output docs_audit_surface.json

Both diffs are exactly the previous commit's four field changes and nothing
more. port_signatures.json: SwaigAction.SWML and SwaigRequest.SWMLCall/SWMLVars
appear; extensive_data and functions_on_speaker_timeout go bool ->
union<string,bool>. docs_audit_surface.json: the same three member names, plus
its `generated_from` provenance line.

The enumerators were run with --out/--output explicitly. Without the flag
enumerate-* writes nothing and still exits 0, which leaves a stale oracle
looking like a clean no-op diff; the 99-module / 2445-method write line is the
receipt that real content landed.
