v0.1.12

Added

• A node with no login of its own can run claude-code and codex stages using the hub's brokered
  provider key. (#51)

Fixed

• Runtime detection retries before concluding a runtime is absent, and re-probes about once a minute,
  tunable with DAHRK_RUNTIME_RECHECK_MS. (#50)
• The boot log states which runtimes were detected and warns when one advertised on the previous boot
  is missing. (#50)
