fix: resolve issues #1888, #1693, #1891

- fix(hooks): skip todo continuation when agent has pending question (#1888)
  Add pending-question-detection module that walks messages backwards
  to detect unanswered question tool_use, preventing CONTINUATION_PROMPT
  injection while awaiting user response.

- fix(config): allow custom agent names in disabled_agents (#1693)
  Change disabled_agents schema from BuiltinAgentNameSchema to z.string()
  and add filterDisabledAgents helper in agent-config-handler to filter
  user, project, and plugin agents with case-insensitive matching.

- fix(agents): change primary agents mode to 'all' (#1891)
  Update Sisyphus, Hephaestus, and Atlas agent modes from 'primary'
  to 'all' so they are available for @mention routing and task()
  delegation in addition to direct chat.
