v0.1.0-alpha.5

Added

• Step recovery markers with irreversible: true and compensatable: false
  for workflows that perform side effects which cannot be safely replayed by
  default.
• Persisted recovery policy on step runs, exposed through run inspection,
  declared step state, and run explanations.
• Replay safety checks that block SquidMesh.replay_run/2 after completed
  irreversible or non-compensatable steps unless the caller passes
  allow_irreversible: true.
• Exported formatter rules for Squid Mesh workflow DSL calls, plus host app
  setup guidance for importing them.

Changed

• Workflow examples and documentation now use the exported DSL formatter style
  without unnecessary parentheses.
• The minimal host app marks its notification step as non-compensatable.

Fixed

• Recovery marker validation no longer emits a misleading conflict error for
  non-boolean marker values.
• Persisted recovery policy normalization now preserves the invariant that
  irreversible steps are non-compensatable.
• Replay approval requires allow_irreversible: true exactly; other truthy
  values no longer bypass the unsafe replay guard.

Notes

• This remains an alpha release. Existing alpha host apps that already installed
  earlier Squid Mesh migrations should reinstall from the current schema or
  apply an equivalent local migration before writing new step runs.
