executus CI / test (push) Has been cancelled
Merges the skill half of the persona/skill pair plus the second nested module. (Squashed onto main from phase-4b-skill; the audit/budget/persona batteries it was stacked on already landed via the P4 merge.) - skill/: clean-redesign Skill noun + LEAN SkillStore (lifecycle/versions/ schedule only) + ToRunnable + Memory default. - contrib/store/: separate go.mod carrying modernc.org/sqlite, so the driver never enters the core go.sum. db.Budget()/Personas()/Skills()/Audit() back all four store seams (JSON-blob + indexed columns; round-trip tested). Includes the verified gadfly #5 fixes (AppendVersion tx+UNIQUE+error, Mark*ScheduledRun atomic json_set, busy_timeout, NaN guard). - CI: builds + tests the nested module and asserts it owns the sqlite driver.
