mise tasks validate

• Usage: mise tasks validate [--errors-only] [--json] [TASKS]…
• Effect: read-only
• Source code: src/cli/tasks/validate.rs

Check task definitions for errors

Checks each task for dependency cycles; references to tasks that do not exist; #USAGE specs that do not parse; invalid timeout values; aliases that more than one task uses; missing or non-executable file tasks; invalid dir paths and templates; missing shell executables; invalid sources and outputs globs; broken task references in run arrays, empty scripts, and tasks with nothing to run; required daemons that no readable [daemons] section declares; and secrets grants that conflict with the sandbox or [env], or, when the config is trusted, that name keys missing from the secrets source.

Exits 1 if any error is found, so you can run it in CI. Warnings are reported but do not fail the command.
