Subject: [PATCH] Autofill deploy version from latest git tag instead of
 hardcoded v0.1.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The deploy.yml workflow_dispatch input always defaulted to 'v0.1.0',
requiring manual edit every time. Now the version defaults to 'auto',
which fetches all tags, finds the latest v* tag via semver sort, bumps
the patch component, and uses that as the deploy tag.

Changes:
- deploy.yml input: default changed to 'auto', required → false,
  description updated to explain both auto and manual modes
- Added 'Resolve version' step: fetches tags, bumps latest semver
  tag by patch, validates output format, exports to $VERSION
- 'Tag version' step: substituted ${{ github.event.inputs.version }}
  → ${{ env.VERSION }} to use the resolved/computed version
- 'Print deploy status' step: same substitution
- Semver validation guard rejects malformed tags (auto and manual)
