1. isAgentNotFoundError now handles:
- Plain objects with .message field (not just Error instances)
- "agent.name"/"undefined" error variants from SDK validation
- The original "Agent not found" format
2. New tests:
- agent.name/undefined error variant triggers fallback
- Plain object errors with .message field trigger fallback
- "fallback also fails" test now verifies retry was attempted (callCount=2)

1. [HIGH] Tool restrictions recomputed for fallback agent via
buildFallbackBody() — no longer inherits original agent's restrictions.
2. [HIGH] Double-retry race prevented — handleSessionErrorEvent now
returns early for agent-not-found errors, since the prompt catch
block already handles them with agent fallback. This prevents
tryFallbackRetry from racing with a model-level retry on the same
error (the "not found" pattern in RETRYABLE_MESSAGE_PATTERNS).
3. [MEDIUM] task.agent updated to FALLBACK_AGENT after successful
fallback — notifications, toast, and logging reflect actual agent.
4. [MEDIUM] FALLBACK_AGENT exported from spawner.ts and imported into
manager.ts — single source of truth.
5. [LOW] resumeTask fallback now uses promptWithModelSuggestionRetry
(consistent with startTask), getting timeout protection.

When a model/mode switch happens while a background task is in-flight,
the oh-my-openagent agent registry can be rebuilt without custom agents
(e.g., Sisyphus-Junior). The SDK then rejects the promptAsync call with
"Agent not found", killing the task.
This adds retry logic: when promptAsync fails with "Agent not found",
retry with the "general" agent (always available in opencode). The
original prompt, model, and skill content are preserved — only the
agent routing changes.
Fixes both the spawner (startTask/resumeTask) and manager (inline
launch) code paths. Also improves the error message detection in
manager.ts to recognize "Agent not found" alongside the existing
"agent.name"/"undefined" checks.

Add support for object-style entries in fallback_models arrays, enabling
per-model configuration of variant, reasoningEffort, temperature, top_p,
maxTokens, and thinking settings.
- Zod schema for FallbackModelObject with full validation
- normalizeFallbackModels() and flattenToFallbackModelStrings() utilities
- Provider-agnostic model resolution pipeline with fallback chain
- Session prompt params state management
- Fallback chain construction with prefix-match lookup
- Integration across delegate-task, background-agent, and plugin layers
Previously, when an explicit model was configured, the agent name was
omitted to prevent opencode's built-in agent fallback chain from
overriding the user-specified model. This removes that conditional logic
and always passes the agent name alongside the model. Tests are updated
to reflect this behavior change.

Implements question-denied session permission rules when creating child
sessions via background task delegation. This prevents subagents from
asking questions by passing explicit permission configuration during
session creation.
🤖 GENERATED WITH ASSISTANCE OF OhMyOpenCode
Child session creation was injecting permission: { question: 'deny' } which
conflicted with OpenCode's child session permission handling, causing subagent
sessions to hang with 0 messages after creation (zombie state).
Remove the permission override from all session creators (BackgroundManager,
sync-session-creator, call-omo-agent) and rely on prompt-level tool restrictions
(tools.question=false) to maintain the intended policy.
Closes#1711
- Deny question prompts in CLI run mode since there's no TUI to answer them
- Inherit parent session permission rules in background task sessions
- Force deny questions while preserving other parent permission settings
- Add test coverage for permission inheritance behavior
