Pull request overview

Adds a project-level auto_update.cooldown_days configuration so prek auto-update can default its cooldown window from the project config (YAML/TOML), with CLI override still taking precedence, and global config as fallback. This fits into prek’s configuration model by extending Config and routing cooldown resolution through workspace/project discovery so each project can be evaluated with its own cooldown.

Changes:

Extend project config model + JSON schema with auto_update.cooldown_days.
Resolve cooldown per project (CLI → project → global → default) and thread it through auto-update’s repo-target evaluation.
Update docs and integration tests/snapshots to cover workspace/project cooldown behavior.

docs/reference/configuration.md:20

The docs describe auto_update.cooldown_days as an unconstrained “integer days”, but the implementation uses u8 (and the JSON schema enforces 0..=255). Document the valid range (or at least note the 255-day maximum) so users aren’t surprised by parse/CLI validation failures for larger values.

Default cooldown for `prek auto-update`.

- Type: integer days
- Default: `0`
- CLI override: `prek auto-update --cooldown-days <DAYS>`

            let filesystem = FilesystemOptions::user()?;
-            let settings = AutoUpdateSettings::resolve(&args, filesystem.as_ref());
-            show_settings!(settings);
+            show_settings!(args);


Preserve resolved settings in auto-update debug output

--show-settings is documented as showing resolved settings, but this branch now calls show_settings!(args) before running auto_update, so it prints only raw AutoUpdateArgs and exits without ever resolving project/global auto_update.cooldown_days precedence. In practice, prek auto-update --show-settings can no longer reveal the effective cooldown when it comes from config files, which is a regression for debugging configuration behavior.
