- Create FileStore trait in crates/notfiles/src/ports.rs capturing all file I/O
operations (read, write, rename, remove, metadata, symlink, etc.)
- Create FileStoreImpl adapter in crates/notfiles/src/adapters/fs.rs wrapping std::fs
- Update linker.rs State::load/save and link_package/unlink_package to accept
FileStore parameter for dependency injection
- Create IdentitySource port in crates/notsecrets/src/ports.rs
- Move IdentitySource trait from sources/mod.rs to ports.rs, maintain backward
compatibility via re-export
- Update all source implementations to import from ports
- Update lib.rs in both crates to re-export ports
- Pass FileStoreImpl through call chain in main.rs and lib.rs public API
Maintains 100% backward compatible public API; FileStore dependency is internal.
Remove hardcoded nu interpreter. HookSpec gains an optional interpreter
field; runner infers from file extension (.sh, .nu, .py, .rb, .zsh,
.bash) when not set. Integration tests now use sh — no nu runtime dep
on CI.
