fix: rename commitlint.config.js to .cjs for ESM compatibility

wagoid/commitlint-github-action v6.2.1 runs with "type": "module"
in package.json, causing .js files to be treated as ESM. The
module.exports syntax requires CommonJS, so rename to .cjs.

+The top-level files and `src/` files are identical — the repo eats its own dog food. CI enforces they stay in sync (except `release.yaml`, which uses template variables in `src/` and hardcoded defaults at the top level).
 
 ## Prerequisites
 
-The release workflow expects the following GitHub org-level vars and secrets:
+By default, the release workflow uses these GitHub org-level vars and secrets:
 
-| Name | Type | Purpose |
+| Name | Type | Default | Purpose |
-|---|---|---|
+|---|---|---|---|
-| `CHRISTMAS_ISLAND_APP_ID` | Variable | GitHub App ID for generating tokens |
+| `CHRISTMAS_ISLAND_APP_ID` | Variable | — | GitHub App ID for generating tokens |
-| `CHRISTMAS_ISLAND_PRIVATE_KEY` | Secret | GitHub App private key |

+    ref: v2.0.0
+    with:

+          GH_APP_OWNER: my-org               # App installation owner
