python-dmon v0.4.0

Release python-dmon v0.4.0.

Added

• Add dmon stack up for supervised stacks with dependency ordering, readiness probes, attached foreground logs, runtime degradation reporting, optional fail-fast behavior, and automatic cleanup.
• Add HTTP, TCP, and command readiness probes.
• Add detached stack supervision with dmon stack up -d, detailed status and listing, and dmon stack down.
• Add detached stack restart with dmon stack restart.
• Add read-only stack log snapshots and following with dmon stack logs and dmon stack logs -f.
• Make foreground stacks discoverable through dmon stack status and dmon stack list, and safely stoppable from another terminal with dmon stack down.
• Add a silent, structured Python API through from dmon import Dmon for task lifecycle and task/stack inspection.
• Add --format json to finite task and stack status/list commands.
• Add dmon wait and Dmon.wait() for configured task readiness, plus direct
  HTTP, TCP, and command waits with finite JSON results.
• Add config-relative env_file loading with ordered layering, dotenv
  expansion, explicit precedence, and support across task, stack, wait, and
  Python API workflows.

Fixed

• Publish start reservations only after their JSON is complete, so concurrent starts never observe a partially written metadata file.
• Retry transient Windows permission errors while atomically replacing metadata
  that another process is reading.
• Keep configured environment values and environment-file paths out of process
  metadata and structured inspection output.
