feat: restore mode-posture energy to expansion + forcing + builder output

Rewrites Writing Style rule 2-4 examples in scripts/resolvers/preamble.ts
to cover three framing families (pain reduction, upside/delight, forcing
pressure) instead of diagnostic-pain only. Adds inline exemplars to
plan-ceo-review (0D-prelude shared between SCOPE + SELECTIVE EXPANSION)
and office-hours (Q3 forcing exemplar with career/day/weekend domain
gating, builder operating principles wild exemplar).

V1 shipped rule 2-4 examples that all pointed to diagnostic-pain framing
("3-second spinner", "double-click button"). Models follow concrete
examples over abstract taxonomies, so any skill with a non-diagnostic
mode posture (expansion, forcing, delight) got flattened at runtime
even when the template itself said "dream big" or "direct to the point
of discomfort." This change targets the actual lever: swap the single
diagnostic example for three paired framings, one per posture family.

Preserves V1 clarity gains — rules 2, 3, 4 principles unchanged, only
examples expanded. Terse mode (EXPLAIN_LEVEL: terse) still skips the
block entirely.

+### 0D-prelude. Expansion Framing (shared by EXPANSION and SELECTIVE EXPANSION)
+
+Every expansion proposal you generate in SCOPE EXPANSION or SELECTIVE EXPANSION mode follows this framing pattern:
+
+FLAT (avoid): "Add real-time notifications. Users would see workflow results faster — latency drops from ~30s polling to <500ms push. Effort: ~1 hour CC."
+
+EXPANSIVE (aim for): "Imagine the moment a workflow finishes — the user sees the result instantly, no tab-switching, no polling, no 'did it actually work?' anxiety. Real-time feedback turns a tool they check into a tool that talks to them. Concrete shape: WebSocket channel + optimistic UI + desktop notification fallback. Effort: human ~2 days / CC ~1 hour. Makes the product feel 10x more alive."
+
+Both are outcome-framed. Only one makes the user feel the cathedral. Lead with the felt experience, close with concrete effort and impact.
+
+**For SELECTIVE EXPANSION:** neutral recommendation posture ≠ flat prose. Present vivid options, then let the user decide. Do not over-sell — "Makes the product feel 10x more alive" is vivid; "This would 10x your revenue" is over-sell. Evocative, not promotional.

 ### 0D. Mode-Specific Analysis
 **For SCOPE EXPANSION** — run all three, then the opt-in ceremony:
 1. 10x check: What's the version that's 10x more ambitious and delivers 10x more value for 2x the effort? Describe it concretely.
