Reads .mokogitea/manifest.xml to detect platform and source directory.
Skips bumps and pre-releases when only workflows, docs, or config

- auto-bump: skips if no source files changed in last commit
- pre-release: skips build if push didn't touch source (dispatch always runs)
- Falls back to always-bump for generic repos without a manifest
