Homero Thompson 5e0e7a4c6a CLI: --help on each subcommand prints its usage and exits 0 (#4538) (#4545)
* 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.
