Public #3029 already landed the generated 30m/12h prompt-cache TTL declarations and the handwritten Responses/browser validators. This PR now adds the remaining regression coverage on top of current main.

The tests cover inline text/image/file blocks passed through the public ResponsesRunnerTurn.supplyOutputs signature without payload casts; omitted TTLs; detached breakpoint snapshots after caller mutation; screenshot TTLs reaching a serialized Responses request; and rejection of invalid TTLs/accessors before pending calls are consumed. No generated declarations or runtime implementations differ from main.

Validation:

• 1,088 focused tests pass on Node 22.22.3 and 24.22.1.
• The inline compile regression produces the original three TS2353 errors against this PR's old generated declarations and passes against current declarations.
• TypeScript checking (tsc --noEmit --module preserve), repository lint, and build pass.
• Local canonical test startup is blocked by SWC rejecting this devbox's filesystem ownership while preparing unrelated example fixtures. Focused tests used a temporary local Vitest configuration omitting that global fixture setup; committed test/CI configuration is unchanged. Hosted CI remains required.

Reviewed the source at 45348ab. The handwritten browser and supplied-output helpers now retain valid 30m and 12h TTL values in detached breakpoint snapshots. Invalid metadata still fails before output registration, and the added regressions cover wire values and later caller mutation. I found no new issues in this runtime change.

The generated public breakpoint types still omit TTL; this approval does not claim that the separate generated-type gap is fixed. I did not run local tests or builds.

Current-head hosted checks include passing Node 22, 24, and 26 tests, lint, builds, the custom-code budget, and OkTest.
