Fixes #11899

Summary

• Fixed opencode run hanging when the model attempts to use the question tool
• The question tool is now properly excluded from the tools list in non-interactive mode

Problem

When running opencode run, if the model tried to use the question tool, it would hang indefinitely because:

1. run.ts correctly sets session permission rules to deny the question permission
2. However, LLM.resolveTools only checked agent.permission when filtering disabled tools
3. Session permissions were ignored, so the question tool remained available
4. When called, Question.ask() waits forever for a response that never comes

Solution

Updated LLM.resolveTools to merge both agent and session permissions when determining which tools should be disabled.

Changes

• packages/opencode/src/session/llm.ts: Added sessionPermission to StreamInput type and updated resolveTools to merge it with agent permissions
• packages/opencode/src/session/prompt.ts: Pass session.permission when calling processor.process()

Verification

Tested locally with bun run dev run "ask me a question using the question tool" - the model no longer attempts to use the question tool.
