ci: skip jobs when unrelated files change, skip Android/Linux when paths unchanged (#144)

- ci.yml: add paths filters to push and pull_request triggers so the full
  Dagger check only runs when source-relevant files change (lib/, test/,
  android/, linux/, scripts/, ci/, Taskfile.yml, etc.).  Pure website,
  docs, and assets/changelog.txt commits no longer trigger ci.yml.

- deploy.yml: add check-changes job that diffs HEAD~1..HEAD and outputs
  android/linux booleans.  On workflow_dispatch both are always true.
  test-android-firebase, deploy-playstore, and deploy-apk are now
  conditional on android==true; build-linux is conditional on linux==true.
  label-deploy-health only fires when at least one build job actually ran
  (not all skipped) and treats 'skipped' as acceptable in ALL_SUCCEEDED.

- ci/main.go Graph(): update Mermaid diagram to reflect the new two-
  workflow structure (ci.yml fast-check + deploy.yml with change-gated jobs).
