feat(sprint2): §2.1/2.2/2.3/2.5 — IP lock/lease, scheduled tasks, retention, versioned snapshot

Browse Source 
§2.1 — IP race with capacity>1 (Invoke-CIJob.ps1)
  Phases 2-3b (clone+start+IP) now run inside a file-based exclusive mutex
  (F:\CI\State\vm-start.lock via FileShare.None). Only one job at a time is
  in the VM-start phase, preventing concurrent vmrun starts from racing for
  the same DHCP lease. After IP is confirmed unique it is written to an IP
  lease file (F:\CI\State\ip-leases\<IP>.lease). Lock is released immediately
  so build phases run fully in parallel. Lease released in finally block.
  Collision detection: if a lease file already exists for the detected IP,
  the job fails fast with a clear error rather than silently sharing a WinRM target.

§2.5 — Versioned snapshot (Invoke-CIJob.ps1 + runner/config.yaml)
  $SnapshotName now defaults to GITEA_CI_SNAPSHOT_NAME env var, falling back
  to 'BaseClean'. config.yaml documents the commented-out variable for snapshot
  refresh workflow (BaseClean_<yyyyMMdd> naming convention).

§2.3 — Artifact/log retention (scripts/Invoke-RetentionPolicy.ps1)
  Purges per-job subdirs under F:\CI\Artifacts and F:\CI\Logs older than
  RetentionDays (default 30). Switches to AggressiveRetentionDays (default 7)
  when F: free space drops below MinFreeGB (default 50 GB). Also removes stale
  IP lease files older than 12 hours (defensive cleanup for crashed jobs).
  SupportsShouldProcess (-WhatIf) for dry-run.

§2.2 — Scheduled task registration (scripts/Register-CIScheduledTasks.ps1)
  Registers two tasks under \CI\ task folder as SYSTEM/HighestPrivilege:
    CI-CleanupOrphans  — every 6h + AtStartup, -MaxAgeHours 4
    CI-RetentionPolicy — daily 03:00 (+30min random) + AtStartup (+15min random)
  Idempotent (-Force), SupportsShouldProcess (-WhatIf), validates script paths.
