- Replaced `atom.sed` string syntax with `{pat,rep,g?,F?,i?}` objects in schema, prompts, and tests.
- Changed sed validation defaults so `pat` is regex, `g` defaults to global replacement, and `F:true` forces literal matching.
- Fixed `sed` edge cases by allowing sequential same-anchor edits, handling zero-length matches, and preserving chaining.
- Updated native build flow to local `--profile` defaults, refactored enum generation, and switched totals to `total_ms`.
