Merge upstream/main into fix/bugfixes

Browse Source 
Resolve conflicts:
- provider.go: keep upstream's serializeMessages (supersedes stripSystemParts)
- provider_test.go: keep upstream's serializeMessages tests
- loop_test.go: add slices import needed by upstream tests
- shell.go: merge PR's --format deny fix with upstream's block device
  pattern, safePaths, and absolutePathPattern
- shell_test.go: include tests from both branches
