Reject unknown and valueless options in cmux hooks setup - #17183
Conversation
cmux hooks setup and uninstall, and the setup-hooks and uninstall-hooks aliases, skip options they don't recognize. A typo such as --agnt=codex with --yes falls back to every agent and writes Pi's extension, and a bare --agent does the same. Refs manaflow-ai#15717
One parser now reads the target and mode for hooks setup, hooks uninstall, and the setup-hooks and uninstall-hooks aliases. It rejects an option it doesn't know, --agent without a value (including --agent= and --agent followed by another flag), and more than one target, before any agent config is touched. --agent <name>, --agent=<name>, --yes/-y, --uninstall and a positional agent keep working. Fixes manaflow-ai#15717
A setup case without --yes reaches Pi's confirmation prompt when Pi isn't installed yet, so an empty stdin keeps it from waiting on the runner.

…t aliases --agent codex --agent pi reused the message about mixing --agent with a positional target, which isn't the conflict, and it wasn't localized. It now says --agent was given more than once with different values. The test also covers the documented agent aliases (agy, rovo) through the positional, --agent and --agent= forms.

Add translations for every locale to all three new error keys.
These entries omit bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and uk, which are already supported in this catalog.
As per path instructions, “additions include complete translations for all existing locale codes in the touched catalog.”

Summary
cmux hooks setupandcmux hooks uninstallskipped any option they didn't recognize, and a bare--agentwas dropped too. When that left no target, the command fell back to every agent. For example,cmux hooks setup --yes --agnt=codexexits 0 and installs Pi's extension, even though the user only meant Codex.cmux hooks setup --agentdoes the same after its prompt. The legacysetup-hooksanduninstall-hooksaliases didn't look at their arguments at all.Now one parser reads the target and mode for all four entry points and stops with a usage error before any config is touched when it sees:
Unknown option --agnt. Usage: cmux hooks setup [agent] [--agent <name>] [--yes|-y]--agentwith no value, including--agent=and--agent --yes:--agent requires a value. Usage: ...--agentgiven twice with different values:--agent was given more than once with different values. Specify one agent.--agentthat disagrees with the positional target (unchanged messages)--agent <name>,--agent=<name>,--yes/-y,--uninstall, a positional agent, and the documented agent aliases (agy,rovo) work as before.runSetupHooksno longer rereads the raw process arguments for--agentand--uninstall. It takes the parsed result. One behavior change:cmux setup-hooks codexused to ignorecodexand set up every agent. It now sets up Codex only, likecmux hooks setup codex.Fixes #15717
