wave3(interview): import skill to 3B + fix dead engine link

[brandonwie]

Summary

Wave 3 sync for the interview skill. Two atomic commits:

1. docs(skills/interview) — replace dead plugins/interview-codex/ pointer (directory never existed in forge) with the real Python engine at plugins/3b/engine/. Adds concrete trigger conditions surfaced by plugin review (numeric scoring 0–1, 40/30/30 weighting, file-locked persisted InterviewState, shared agents/ SSoT).
2. chore(manifest) — record 11 new SOURCE-MANIFEST entries for the Wave 3 interview-skill sync (1 SKILL + 3 references + 7 perspectives). 3B is canonical (matches Wave 2 direction). Top metadata bumped: synced_at → 2026-04-26, three_b_head_at_sync → c547ebfe.

Context

Companion to 3B branch feat/embed-interview-skill which imports the skill into 3B as canonical. Drift script (scripts/check-3b-drift.sh) shows 29/29 entries pass.

Forge agents/ layout (plugin-root) differs from 3B's nested layout (.claude/skills/interview/agents/) — drift script compares content not paths so divergence is intentional.

Test plan

• bash scripts/check-3b-drift.sh → 29/29 pass
• grep -rn 'interview-codex' plugins/3b/skills/interview/ → no stale references
• forge engine path verified: plugins/3b/engine/{README.md,src,tests,pyproject.toml} exist

Summary by CodeRabbit

• Chores

  • Advanced internal synchronization metadata to Wave 3 with expanded configuration mappings for system integration

• Documentation

  • Updated implementation guidance clarifying ambiguity scoring methodology on a 0-1 scale with specified weighting, state persistence mechanics, and shared resource references for programmatic integrators

Changes:

• Update interview skill docs to replace a dead plugins/interview-codex/ pointer with the actual Python engine location at plugins/3b/engine/, and document scoring/state details.
• Bump manifest top metadata (synced_at, three_b_head_at_sync) for the Wave 3 sync.
• Add 11 new Wave 3 manifest entries (skill, references, and agent perspective files) pointing at the canonical 3B sources.
