feat(rfc): Section 18 — Action and Task execution primitives
Action = named, registered callable. The atomic unit of work.
Task = composition of Actions (chain, parallel, conditional, scheduled).
Key design:
- c.Action("name", handler) registers, c.Action("name").Run() invokes
- Services register actions during OnStartup (same as commands)
- Namespace IS capability map (process.*, agentic.*, brain.*)
- Registration IS permission — no action = no capability
- Current IPC verbs (ACTION/QUERY/PERFORM) become invocation modes
- c.Process() is sugar over process.* actions
- Tasks compose Actions into flows (sequential, parallel, conditional, cron)
- Action registry is queryable — agents inspect capabilities before using
Sections: 18.1-18.10 covering concept, API, registration, permission,
task composition (chain/parallel/conditional/scheduled), IPC mapping,
process integration, and registry inspection.
