fix: editor split, stop flag in actions, write errors, history on failure, expect panic, string match

- src/main.rs: split VISUAL/EDITOR into prog+args, drop expect panic in reap_timer, propagate write_timer errors, check stop during actions, record history on partial failure, use const for stop msg
- Cargo.toml: add authors/homepage, bump noyalib 0.0.12->0.0.13
- release.yaml: tighten tag glob, fix curl 404 fallback, URI-encode asset name, upgrade upload-artifact v3->v4
- ci.yaml: add cargo cache step
- README.md: sync feature list, fix push to two-step
- RELEASING.md: clarify Cargo.lock regeneration
