Add another GitHub workflow to run CI tests every night (and manually)

[christoph-jerolimov]

Create a new ci-nightly GitHub workflow with steps similar to the ci workflow, but it should run this every night (cron) and manually triggered (workflow_dispatch).

The workflow should have an optional input parameter workspaces. It should be parsed as json with a string array. When it's not defined all workspaces should run. Read other workflows and scripts/ci folder.

For the workspaces a new matrix job should then run all verifications from ci. Incl tsc, build, test, e2e tests.

Triage Summary

Category: Feature request · Severity: Medium

Problem

The repository currently runs CI only on pull requests for changed workspaces. There is no scheduled workflow to catch regressions across all workspaces from dependency updates or transitive breakage.

Recommended Implementation

Create .github/workflows/ci-nightly.yml with the following structure:

• Triggers: schedule (cron, e.g., 0 2 * * *) and workflow_dispatch
• Input: Optional workspaces parameter — a JSON string array (e.g., ["theme", "lightspeed"])
• Default behavior: When workspaces is not provided, discover and run all workspaces (reference existing scripts in scripts/ci/)
• Matrix jobs: For each workspace, run the same verification steps as the existing ci.yml workflow — including tsc:full, build, test:all, prettier:check, lint, API reports, and Playwright e2e tests
• Node versions: Match the existing CI matrix (Node 22 and 24)

The existing ci.yml workflow and scripts/ci/ folder provide clear templates. The main difference is replacing the PR-based change detection with either a full workspace list or the user-supplied workspaces input.

Proposed Test Plan

1. Trigger via workflow_dispatch with NO workspaces input
   → Verify all workspaces appear in the matrix

2. Trigger via workflow_dispatch with workspaces = '["theme","lightspeed"]'
   → Verify only those two workspaces run

3. Confirm the cron schedule appears correctly in the Actions tab
