* fix(skill-creator): tolerate non-object timing measurements
Treat optional timing JSON values that are not objects as missing measurements so they cannot abort benchmark aggregation. Preserve grading durations, character-count fallback and recorded zeros; add regression coverage for both layouts and subsequent runs.
* fix(skill-creator): warn and validate timing measurements
* fix(skill-creator): tolerate unreadable timing files

* fix(skill-creator): preserve recorded token counts in benchmarks
Read timing.json token measurements independently of grading duration and retain recorded zero values. Keep the existing character-count fallback for missing measurements and add benchmark/report regression coverage.
* fix(skillscan): distinguish token metrics from credentials
Recognize typed token counts, numeric benchmark summaries, and signed deltas so skill-creator documentation passes deterministic review. Preserve credential names, string values, duplicate-key detection, and cloud-token findings; add regression coverage and document the boundary.
