Replace PreToolUse hook-based question tool blocking with the existing
tools parameter approach (tools: { question: false }) which physically
removes the tool from the LLM's toolset before inference.
The hook was redundant because every session.prompt() call already passes
question: false via the tools parameter. OpenCode converts this to a
PermissionNext deny rule and deletes the tool from the toolset, preventing
the LLM from even seeing it. The hook only fired after the LLM already
called the tool, wasting tokens.
Changes:
- Remove subagent-question-blocker hook invocation from PreToolUse chain
- Remove hook registration from create-session-hooks.ts
- Delete src/hooks/subagent-question-blocker/ directory (dead code)
- Remove hook from HookNameSchema and barrel export
- Fix sync-executor.ts missing question: false in tools parameter
- Add regression tests for both the removal and the tools parameter
OpenCode TUI reads input.subagent_type to display task type. When
subagent_type was missing (e.g., category-only or session continuation),
TUI showed 'Unknown Task'.
Fix:
- category provided: always set subagent_type to 'sisyphus-junior'
(previously only when subagent_type was absent)
- session_id continuation: resolve agent from session's first message
- fallback to 'continue' if session has no agent info
