feat(cli): add integrity command group with generate/verify/hash/diff

- Add IntegrityCommands enum with dedicated subcommands
- Implement `wharf integrity generate` for BLAKE3 manifest creation
- Implement `wharf integrity verify` for local and remote validation
- Implement `wharf integrity hash` for single file hashing
- Implement `wharf integrity diff` for manifest comparison
- Update STATE.scm with session accomplishments

The integrity commands provide comprehensive file integrity management:
- generate: Create manifests with configurable exclusions
- verify: Validate against manifests locally or via SSH to remote yachts
- hash: Quick BLAKE3 hash of individual files
- diff: Compare two manifests showing added/removed/changed files
