We now apply semantic version tags deliberately (see v1.7.19–v1.9.2), so the
daily auto-bump is no longer wanted.
- Drop the `schedule:` cron (and the now-unneeded DST guard) — the workflow
runs only on `workflow_dispatch`, with patch/minor/major options.
- Remove the Slack notification entirely: the "Update changelog canvas" and
"Post to Slack" steps (and the PR/bullet collection that fed them) are gone,
along with their SLACK_* secret usage.
- Keep the core behavior: compute the next version from the latest tag + chosen
bump and push an annotated tag.
Renames the workflow "Daily Version Bump" -> "Version Bump".
The date comparison used git's author date in its stored timezone
(e.g. -04:00) against GitHub API mergedAt values in UTC (Z suffix).
Lexicographic string comparison across different timezone formats
caused every PR from the tagged commit's day to be re-included in
subsequent versions. Normalize to UTC with format-local so both
sides match.
Also replace the hardcoded canvas URL with the CANVAS_ID env var
already available in the step.
Reworks the daily version bump workflow to:
- Pull merged PR titles via gh CLI instead of raw commit messages
- Post a polished, non-technical channel message with a link to the
changelog canvas
- Prepend the new version entry to the Slack canvas via canvases.edit
API so the canvas stays in sync automatically
Channel message format:
"After-Hours Scheduler has been updated to vXXXX.XX.XX

Replaces per-push notifications with a daily 6pm ET cron job that
batches all commits since the last version tag into a single Slack
message. Tags main with a date-based version (v2026.05.01) so there
is at most one version bump per day. Includes DST guard matching the
pattern used by the other scheduled Lambdas.
