feat: add nightly update mode to auto-update workflow

[tomusdrw]

Summary

• Add a workflow_dispatch input to select between tag (latest release) and nightly (latest main branch) update modes
• Nightly mode compares and checks out the graypaper-archive main branch SHA instead of release tags
• Skip GitHub release creation for nightly updates

Test plan

• Trigger workflow manually with tag mode and verify it behaves as before
• Trigger workflow manually with nightly mode and verify it tracks the main branch SHA
• Verify scheduled runs default to tag mode

📝 Walkthrough

Walkthrough

A GitHub Actions workflow enhancement that introduces an update_mode input option (tag or nightly) to support two update detection strategies: release tag-based updates or continuous builds from the main branch. The workflow logic, versioning, and release creation steps are conditional based on the selected mode.

Summary

Workflow Dispatch Configuration & Update Mode Handling .github/workflows/auto-update.yml

Added workflow_dispatch.inputs.update_mode parameter with tag and nightly options. Threaded mode through workflow via check_for_updates job output and UPDATE_MODE environment variable in update job. Modified update detection logic to compare commit SHAs in nightly mode vs. tag names in tag mode. Updated archive checkout and versioning to handle both modes, with nightly mode setting version to nightly-$shortSHA. Conditional release creation now skipped when mode is nightly.

Poem

🐰 A workflow now dances in dual-mode delight,
Between nightly whispers and tag-based might,
SHA hops and releases align in their track,
The automation evolves, never looking back! ✨

80-95: ⚠️ Potential issue | 🟠 Major

Refresh the repo’s Graypaper-derived files before committing.

This step updates the archive checkout, but the workflow never runs the Graypaper sync/copy step before the later git add .. That means the PR can merge a new archive revision while leaving copied/generated repo content stale.

Based on learnings, run git submodule update --init && npm run cp-gp whenever the Gray Paper archive changes.

- Around line 28-29: The workflow currently re-evaluates origin/main during the
update job and may checkout a different tip than the SHA used by
check_for_updates; instead, capture the resolved remote commit SHA in the
check_for_updates job output (e.g. remote_release.outputs.VERSION or a new
remote_release.outputs.COMMIT_SHA) and make the update job use that exact SHA
when checking out or creating the PR in nightly/update_mode (referencing
steps.remote_release.outputs.COMMIT_SHA in the update job instead of refetching
origin/main); apply the same change to the other occurrence noted (the block
around lines 84-88) so both code paths use the pinned remote SHA rather than
re-querying the branch tip.
