chore: use cargo-nextest as the test runner

- .config/nextest.toml: hang-timeout profile (warn 60s, kill 120s)
- justfile: 'just test' = cargo nextest run --workspace + cargo test --doc
- CLAUDE.md: refresh stale Status + Commands for the real workspace + nextest

163 tests run in ~7s (vs multi-minute serial cargo test).

 ## Status
 
-Freshly scaffolded Rust binary crate (edition 2024). `src/main.rs` is still the `cargo new` "Hello, world!" stub and `Cargo.toml` has no dependencies yet. There is no architecture to document — update this file as real structure emerges.
+Rust (edition 2024) workspace + React SPA collection-management system. Backend crates: `domain`, `db`, `api`, `auth`, `search`, `server` (axum 0.8 + sqlx/Postgres + Meilisearch). Frontend in `web/` (React 19 + Vite + pnpm). Tests need the docker-compose stack up (Postgres on **:5442**, Meilisearch on **:7700**); each `#[sqlx::test]` provisions its own temp DB.
 
 ## Commands
 
 ```bash
-cargo build              # build
-cargo run                # run the binary
-cargo test               # run all tests
-cargo test <name>        # run a single test by name substring
+just check                       # fmt + lint + test — the standard pre-commit gate
+docker compose up -d             # start Postgres (:5442) + Meilisearch (:7700) for tests
+cargo build --workspace          # build
+cargo run -p server              # run the server (or: just run — loads .env)
+cargo nextest run --workspace    # run all tests — PREFERRED (per-test isolation, live output, hang timeouts)
+cargo nextest run -E 'test(<name>)'   # run tests matching a name substring
+cargo test --workspace --doc     # doctests (nextest does not run these)
 cargo +nightly fmt               # format — always nightly, not stable
-cargo clippy             # lint before committing
+cargo clippy --workspace --all-targets -- -D warnings   # lint before committing
 ```
 
+(`just test` runs nextest + doctests; config in `.config/nextest.toml`.)

 ## Conventions
 
 - **CLI args & env vars:** use `clap` with the `derive` feature.
