feat(build): GitLab CI component, GitHub Actions action, and pre-commit hook

templates/check.yml — GitLab CI/CD Catalog component; downloads the glint
Linux binary and runs glint check; inputs: stage, pipeline_file, version,
allow_failure, extra_args.

action.yml — GitHub Actions composite action; downloads glint into
$RUNNER_TEMP and runs glint check; inputs: version, file, args. Mirror
to github.com/k3nny/glint to use as `uses: k3nny/glint@vX.Y.Z`.

.pre-commit-hooks.yaml — language: golang hook; pre-commit builds glint
from source on first run and re-runs on staged .gitlab-ci.yml changes.
Reference as repo: https://git.k3nny.fr/k3nny/glint.

README updated with an Integrations section covering all three.
Git remote corrected to https://git.k3nny.fr/k3nny/glint.

+## Integrations
+
+### Pre-commit hook
+
+Add to `.pre-commit-config.yaml` in your repository to run glint automatically whenever `.gitlab-ci.yml` changes:
+
+```yaml
+repos:
+  - repo: https://git.k3nny.fr/k3nny/glint
+    rev: v0.2.28
+    hooks:
+      - id: glint
+```
+
+Requires [pre-commit](https://pre-commit.com) and Go 1.21+. On first run, pre-commit builds glint from source automatically.
+
+### GitLab CI component
+
+Copy [`templates/check.yml`](templates/check.yml) into your repository and include it as a local file, or publish this repository to a GitLab CI/CD Catalog and reference it as a component:
+
+```yaml
+# As a local include (copy templates/check.yml to your repo first):
+include:
+  - local: .gitlab/glint-check.yml
+
+# As a Catalog component (after publishing to a GitLab instance):
+include:
+  - component: $CI_SERVER_FQDN/k3nny/glint/check@v0.2.28
+    inputs:
+      stage: validate          # optional, default: validate
+      allow_failure: true      # optional, default: false
+```
+
+The component downloads the glint Linux binary, runs `glint check`, and respects all inputs defined in the `spec:` block.
+
+### GitHub Actions
+
+Copy [`action.yml`](action.yml) from this repository, or mirror this repo to GitHub as `k3nny/glint` and reference it directly:
+
+```yaml
+- uses: k3nny/glint@v0.2.28
+  with:
+    file: .gitlab-ci.yml   # optional, default: .gitlab-ci.yml
+    args: '--format sarif' # optional
+```
+
+The action downloads the glint Linux binary into `$RUNNER_TEMP` and runs `glint check`. Only Linux runners are supported (matches the available release binary).

 ## Development
 
 This project uses [Task](https://taskfile.dev) as a task runner.
