zagent 0.0.226

• Kernel-parity reasoning-level resolution: --effort and per-turn model
  options now resolve reasoning levels against the merged
  modelConfigRules sets in kernel order with scoped
  apiType/baseUrl/template/provider matching (previously a z.ai-site
  catch-all could leak one site's vocabulary onto unrelated builtin
  models). Legacy reasoning.defaultLevel/reasoning.levels{} and
  array forms still resolve, with the declared default ordered last.
• --effort is validated against the resolved per-model vocabulary
  before spawn: an unsupported level is refused with exit 2 instead of
  being forwarded to the kernel; the static built-in level list now
  only applies as a null-catalog fallback and for --effort without
  --model. The same validation applies to zagent commit-msg and the
  MCP zagent_turn tool (whose schema enum no longer overstates the
  levels for non-plan vocabularies).
• --effort --help text now discloses that the default is the model's
  last declared level.
