* claim: #4538 * CLI: --help on each subcommand prints its usage and exits 0 (#4538) Every command now answers `--help` and `-h` with its own usage on stdout and exit 0, the way the top level has since #1828. Before, each subcommand answered differently: `fuzz --help` started a fuzz run with the default seeds and ran until it was stopped, `recipe --help` took the flag for a file name, and `snapshot`, `render`, `oracle`, `run`, `eval`, `script` and `crashes` answered with an error on stderr and exit 1. The help is read before the command runs, so `--help` never starts work: no fuzz run, no MCP server, no file read. `fuzz` also refuses an argument it doesn't take, as `snapshot` already did: a flag it doesn't know and a stray word are errors, not arguments to ignore while a hundred seeds run. The usage lives in one place now: each command's lines are a constant, and the top-level usage is composed from them, so the two cannot drift apart. The top-level usage is unchanged, byte for byte. # Conflicts: # apps/solidcraft-cli/src/main.rs
