chore: remove dead workflows tied to the now-deleted master branch (#12)

master was confirmed unused before deletion: no webhook/deploy-key
writes to it, no branch protection, last commit 2026-03-10 (4 months
stale), and no open PR targeted it. Its content was already fully
contained in main's history (main had since diverged far ahead with
v1.0.2/v1.0.3 releases), so nothing was lost.

These four workflows existed solely to serve or react to that branch
and can never trigger again now that it's gone:
- auto-pr.yml / auto-merge.yml: the master->main sync mechanism
  itself - its entire purpose is gone along with master.
- pr_workflow.yml: triggers on `pull_request: branches: [master]`
  (rc/hotfix release-notes automation) - can't fire, no PRs target
  master anymore.
- update_tag.yml: triggers on `push: branches: ['master']` (auto
  version tagging) - can't fire either.

The last two encode logic (release-notes extraction, auto-tagging)
that might still be wanted against main - left that as a separate
decision rather than silently re-pointing them, since that would
activate new automation behavior nobody asked for here.

Deliberately not touching .github/workflows/appium-mobile-tests.yml's
`ref: 'master'` - that's a workflow_dispatch call into a *different*
repository (pezkuwichain/appium-mobile-tests) and has nothing to do
with this repo's now-deleted branch.
