chore(ci): repoint push-email-notify to smtp-notify-action

[hyperpolymath]

Replaces dawidd6/action-send-mail with hyperpolymath/smtp-notify-action v0.2.0 (tag commit ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7), per the 2026-09-02 ruling (standards spec §5.5/§9, PR hyperpolymath/standards#725). The whole file is replaced with the rsr-template-repo canonical, which — besides the uses: line — restricts the trigger to branch pushes (tag and deletion payloads mislabel Branch:/head_commit), sets timeout-minutes: 5, carries a deliberately per-run concurrency group, and grants only contents: read. How many of those are actual changes here depends on how far this repo's copy had drifted — read the diff, not this list. Dormant gating on vars.PUSH_EMAIL_ENABLED == 'true' is unchanged. Line 1 SPDX header kept as it was.

Engine: .git-private-farm/scripts/smtp-notify-sweep.sh. Verification for this repo: regime=no-lock changed=.github/workflows/push-email-notify.yml, sig=G 0860a42 canon=543fc1474b54 base=main
(pristine/post = gh actions-lock --no-fix validity before/after; repair = the lock was already invalid before this change and is valid after it.)

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • Push email notifications now run only for branch pushes, avoiding unnecessary notifications from other push events.
  • Notification runs are managed independently, preventing queued notifications from being cancelled and lost.
  • Added a five-minute time limit to prevent stalled notification jobs.

Walkthrough

The push email workflow now processes branch pushes only, keeps each run independent, limits notification jobs to five minutes, and uses a pinned SMTP notification action.

Changes

Push email notifications

Layer / File(s)	Summary
Workflow trigger and concurrency .github/workflows/push-email-notify.yml	The workflow documents its reinstatement, restricts triggers to branch pushes, and assigns each run a non-cancelling concurrency group.
Notification action execution .github/workflows/push-email-notify.yml	The notify job adds a five-minute timeout and switches to the pinned hyperpolymath/smtp-notify-action while retaining the existing SMTP parameters.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk:🔵 Low · up to 0860a

The new mail action may fail to deliver push notifications if the configured SMTP service uses STARTTLS or an unsupported authentication method. Confirm the endpoint configuration before enabling notifications.

Poem

A rabbit checks the branch-mail trail
Each run hops on its own bright rail
The SMTP carrot waits in line
Five minutes keeps the timing fine
Pinned paws send every sign

15-15: 🎯 Functional Correctness

No change required.

Branch deletion does not trigger a push workflow. This workflow therefore cannot process a deletion through the configured push trigger.

Confirm SMTP endpoint compatibility before enabling notifications.

When PUSH_EMAIL_ENABLED is true, this workflow uses implicit TLS and AUTH PLAIN. If secrets.SMTP_HOST and secrets.SMTP_PORT target a standard port-587 STARTTLS service, or a provider that supports only AUTH LOGIN or XOAUTH2 such as Microsoft 365, the step can fail and send no notification. Use a compatible implicit-TLS endpoint that supports AUTH PLAIN.
