fix(P01): replace hardcoded phase=1 in orchestrator and fix getDecisions double-fetch

---ci---
project: ci
phase: 1
milestone: v0.8
status: in_progress
decisions:
  - id: D-021
    decision: 6-phase wave-ordered vertical slices for v0.8
    rationale: Each phase independently demoable; critical fixes first
    confidence: 0.90
requirements:
  covered: [FIX-01, FIX-06]
---/ci---

FIX-01: Replace 5 hardcoded phase=1 literals in orchestrator.ts mechanical
execution path with this.pipelineState!.current_phase. The orchestrator
correctly tracks current_phase but commits always embedded literal 1.

FIX-06: Replace getDecisions() redundant double-fetch with single
getRecentCommits(50) call, delegating to existing getDecisionsFromCommits().
Old code called getRecentCommits(50) once per grep match entry (O(N*M)
when it should be O(1)).
