gentle-pi v0.4.3

What's Changed

• Add a Pi-shaped SDD status contract and read-only sdd-status agent.
• Enforce persisted task completion parity: sdd-apply owns task checkbox updates, while verify/archive validate and block stale unchecked tasks.
• Preserve sdd-sync as the canonical sync-before-archive phase while adding status/actionContext guards.
• Include package/runtime verification for installed status support assets and drift detection.

Validation

• pnpm test
• node scripts/verify-package-files.mjs
• pnpm publish --dry-run --no-git-checks
