Description

## Description

Migrate src/commands/service/ipc.rs handle_spawn (IPC spawn entry) to call workgraph::dispatch::plan_spawn() for executor/model/endpoint resolution.

File scope: src/commands/service/ipc.rs only.

Implement directly — do not decompose further.

## Validation
- [ ] handle_spawn calls plan_spawn for executor/model/endpoint
- [ ] Provenance log line emitted on every IPC-driven spawn
- [ ] cargo build + cargo test pass with no regressions

Log

• 2026-04-26T20:42:29.585889268+00:00 Lightweight assignment: agent=Careful Programmer (f5143935), exec_mode=full, context_scope=task, reason=Careful Programmer's 41-task track record and reliability focus are well-suited for this correctness-critical refactoring that must maintain no regressions while migrating IPC spawn logic.

• 2026-04-26T22:55:15.186792476+00:00 Migrated handle_spawn to plan_spawn: loads task+config, resolves agent_executor (agency-derived OR IPC hint), calls plan_spawn for {executor, model, endpoint}, emits provenance via logger.info, then dispatches resolved values to spawn_agent. Updated call site in handle_request to pass logger.
• 2026-04-26T22:55:17.563434721+00:00 Validated: cargo build --bin wg succeeds; cargo test --lib passes (1943/1943); cargo test --bin wg passes (2821/2822, 1 pre-existing unrelated failure provenance_full_lifecycle_all_ops_recorded — unchanged baseline). dispatch::plan tests all pass including test_executor_floor_is_honored regression test.
