Phase A: agent-neutral prose + CSO → SDO + spec

Replace generic third-person "Claude" with "agents" / "your agent"
forms across active skill prose, the README intro, and the vendored
anthropic-best-practices.md reference. Carve-outs preserved:
historical attribution paths, the "Variant C: Claude.AI Emphatic
Style" example label, model identifiers (Haiku/Sonnet/Opus), and the
"In Claude Code:" per-platform skill-dispatch list.

Coined-term rename: "Claude Search Optimization (CSO)" → "Skill
Discovery Optimization (SDO)" in writing-skills/SKILL.md.

Files in this commit also pick up later-phase changes that
accumulated on the same files (dispatching-parallel-agents code-
example transformation, writing-skills numbering and path fixes).
The bundled spec at docs/superpowers/specs/ records the original
scope and the carve-outs.

README.md gets only its prose change here; the alphabetization
lands in Phase C's commit.
