chore(spec): align 2025 anchor provenance with release pin

[squarepots]

What

Regenerate the 2025 spec anchor provenance header from its configured release pin.

Why

scripts/fetch-spec-types.ts pins released 2025 generation to 0168c57fc74aba6e6dcf8f0b7191db3caaa5ad65, while the checked-in generated header still records 357adac47ab2654b64799f994e6db8d3df4ee19d.

Both commits point to the same schema/2025-11-25/schema.ts Git blob (332c3f0edaf78311e8e9b3a4df4c0785533cbc0e), so this changes provenance only.

The result is that regenerating the released 2025 anchor from its configured default authority no longer produces a spurious header diff.

Validation

• one generated file changed;
• only the recorded source commit changed;
• the upstream schema blob is identical at both commits.
