- `glint explain <RULE>`: new subcommand printing rule description,
rationale, bad-YAML example and fix for every GL001–GL043 rule.
`glint explain` (no arg) lists all rules with ID, severity, title.
Rule IDs are case-insensitive.
- GL042 (rules:if: evaluated reachability): warns when every rules:if:
condition evaluates to false given the values of variables declared in
the pipeline YAML, making the job statically unreachable. Conservative:
only fires when all referenced variables are declared in YAML; predefined
CI_* / GITLAB_* variables are skipped to avoid false positives.
- GL043 (inherit: completeness): warns when inherit: default: is declared
but there is no default: block in the pipeline (dead declaration), or
when the list form names fields not set in the default: block.
