Improve Versioning Discipline & Release Automation

[ZFordDev]

Summary

SnapDock currently uses manual SemVer versioning (MAJOR.MINOR.PATCH). While this is valid and compliant, the process is fully manual and not integrated with the build or release workflow. This issue proposes improving versioning discipline and automating release steps.

---

Problem

Manual versioning leads to:

• inconsistent bumping
• risk of forgetting to update version
• no automated changelog
• no automated tagging
• no CI‑driven release flow
• no link between commits and version numbers

This is outside the scope of #120, but should be addressed in a future milestone.

---

Goals

• Enforce SemVer bump rules
• Automate version bumping
• Automate changelog generation
• Automate Git tags
• Integrate versioning with CI
• Ensure version metadata is consistent across:
  • package.json
  • build artifacts
  • release notes
  • updater metadata

---

Non‑Goals

• No changes to artifact naming
• No changes to build section
• No changes to platform overrides
• No changes to signing

---

Notes

This issue is intentionally separate from build‑system cleanup to keep #120 focused and clean.
