v0.6.0

Phase 4 of the rauf UX/DX overhaul — web/CLI recovery parity, a shared status
vocabulary, and a ratified agent contract. Additive minor bump (no
minRunnerVersion change, no feature-forge lockstep).

Added

• Web recovery parity with the CLI: reset, resume, review, unblock,
  and validate are now exposed as web server routes with matching status-page
  controls, so the dashboard can drive the same loop-recovery operations the CLI
  offers.
• Shared status label-map across CLI and web — REVIEWING and
  PAUSED_USAGE_LIMIT badges and a "Needs Human" label render identically in
  both surfaces.
• rauf update --check — report-only drift audit that prints whether a
  project's artifacts are stale (tool-version lag or dead hash keys) and exits
  non-zero if so, writing nothing. Makes fleet-wide staleness scriptable.

Changed

• status exit codes are aligned with the unified scheme via a shared
  statusExitCode mapping, so the web DerivedStatus and CLI agree on outcome
  semantics.
• Agent-contract documentation finalized and the UX-overhaul canon ratified
  (canon-conformance review: GO, 0 blockers).
• rauf update now prunes stale artifact-hash keys from the marker (e.g. the
  legacy ralph.sh/ralph-status.sh/ralph-add.sh hashes carried over from a
  pre-rename install) instead of preserving them indefinitely.
• rauf migrate documentation sharpened as a legacy one-shot (it renames
  structure but does not backfill artifacts — follow with rauf update; non-rauf
  config references to .ralph are reported but not auto-rewritten).

Removed

• rauf update --yes retired from --help — update is non-destructive and
  never prompts (the flag is still tolerated for back-compat).
