Issue: Missing docs/conversion.mdx update

This PR changes conversion logic for Claude question events but does not update docs/conversion.mdx as required by CLAUDE.md line 39:

"Update docs/conversion.md whenever agent-native schema terms, synthetic events, identifier mappings, or conversion logic change."

Changes requiring documentation:

1. Changed conversion flow: Question replies now route through permission control response (instead of tool_result) when a linked permission exists (router.rs:2193-2240)

2. New synthetic events: Both PermissionResolved and QuestionResolved events are now emitted for question tools (router.rs:2254-2274)

3. Event suppression: Permission events for question tools (AskUserQuestion, ExitPlanMode) are suppressed from frontends (router.rs:697-707)

4. Identifier mappings: New is_question_tool_action() helper maps casing variations to question handling logic (router.rs:5207-5223)

The current docs/conversion.mdx states that question.resolved maps to tool_result (AskUserQuestion), which is no longer accurate. Please update the documentation to reflect:

• Permission control response routing for question answers
• Synthetic PermissionResolved events alongside QuestionResolved
• ExitPlanMode as a question tool (not just AskUserQuestion)
• Suppression of question-tool permissions from frontends
