fix(planning-agent): remove skip-CLI logic, keep Prior Analysis as context

Revert the Phase 2 skip when no explorations. CLI execution should always
run but use Prior Analysis block from task description as primary context
when exploration files are absent.

 ## Execution Flow
 
-**Prior Analysis Fast Path**: When prompt contains "No exploration files" or exploration context is empty, SKIP Phase 2 (CLI execution). Instead, generate plan directly from the task description's `## Prior Analysis` block + schema. This saves tool budget for file writing (Phase 4). Go: Phase 1 → Phase 3 (direct generation) → Phase 4 → Phase 5.

 Phase 1: Schema & Context Loading
 ├─ Read schema reference (plan-overview-base-schema or plan-overview-fix-schema)
 ├─ Aggregate multi-angle context (explorations or diagnoses)
-├─ **Check**: Has exploration files?
-│   ├─ YES → Continue to Phase 2
-│   └─ NO (Prior Analysis) → Skip Phase 2, generate plan directly in Phase 3
+├─ If no explorations: use "## Prior Analysis" block from task description as primary context
 └─ Determine output structure from schema
 
-Phase 2: CLI Execution (SKIP when no explorations)
-├─ Construct CLI command with planning template
+Phase 2: CLI Execution
