Plan a standalone `skaza` Rust crate under `crates/skaza/` that discovers Rust mutation candidates without executing them, copying and simplifying the Rust-only source discovery, six mutation operators, Tree-sitter queries, candidate deduplication, and skip rules from Ooze. The plan defines the `--src`/`--limit`/`--format` CLI contract, acceptance criteria AC1-AC11, and independent Skaza flake checks, while narrowing the CLI Nix source fileset so Skaza edits leave `sce` derivations unchanged. Mutation application and execution are deferred to a follow-up. Plan: skaza-rust-mutation-discovery Tasks: T01-T08 (added, status:todo) Co-authored-by: SCE <sce@crocoder.dev>
Introduce the standalone `skaza` package under `crates/skaza/` as the foundation for discovery-only Rust mutation candidate finding. It ships its own lockfile and is not part of a root workspace, so `cli/` stays untouched. `skaza::Args` (clap derive) exposes exactly `--src` (repeatable, default `.`), `--limit` (`NonZeroUsize`, default 10, actionable error on 0 or non-numeric input), and `--format` (`text`|`json`, default `text`), with no subcommands. `main.rs` only parses arguments; the `source`, `mutation`, `rust`, and `report` modules are empty placeholders, and `queries/rust/` and `tests/` are reserved. Unit tests cover defaults, repeated `--src`, explicit values, zero/non-numeric limit, invalid format, and subcommand rejection. Ignore `crates/skaza/target/`.
