New shared `maestro-names` crate producing `adjective-instrument` session
handles drawn from the orchestra pit — musical tempo/dynamics/articulation
markings × instruments and forms (e.g. `allegro-cello`, `crescendo-oboe`,
`staccato-viola`), tying handles to the app's conductor metaphor.
- Pure generation takes an injected RNG; no thread_rng/clock in pure paths,
so seeded tests are reproducible (repo invariant).
- `generate_unique` prefers the bare name, appending an incrementing numeric
suffix (`-2`, `-3`, …) only on collision via an injected `is_taken`.
- `generate_thread` is the one impure convenience wrapper for runtime callers.
- Wordlists are public so the web UI can mirror them for instant reroll; the
Rust generator stays the source of truth.
Closes#23. Part of #21 (spawn dialog rework).
