Collapse `prove-rs` into `prove`: - ProveRSOpts merged into ProveOpts - `kmir prove` is the primary command (`prove-rs` kept as alias for backwards compatibility) - adds `parsed_smir` option for programmatic use (useful for tests with many start symbols like #985)
This is needed while we still have `thunk` in the semantics to catch UB
Tested with `time make test-verify-rust-std TEST_ARGS='-k unchecked_add'` which resulted in a 17.8% reduction in time (110.643 seconds): - Before: 10m22.304s - After: 8m31.661s

--terminate-on-thunkPart 3 (floats) is blocked: KMIR lacks float value support. Harnesses exist in to_int_unchecked-fail.rs and should be moved to to_int_unchecked.rs once passing.
