vault: add GSD methodology deep-dive with examples and zettelkasten insights

Comprehensive GSD analysis: 15 sections covering core philosophy (fresh
context per agent), 5 methodologies (dream extraction, goal-backward
verification, nyquist validation, wave execution, checkpoints), full
command reference (37+), agent system (16 agents with model routing),
config system, git integration, state management, session continuity,
community best practices, pitfalls, framework comparison (GSD vs ECC vs
BMAD vs SpecKit), and 4 detailed practical examples (new project, brownfield,
debugging, quick tasks).

Three zettelkasten notes: context rot vs window isolation tradeoffs,
goal-backward vs forward verification, plans-as-prompts design pattern.

# 目标回溯验证 vs 正向任务检查
传统软件验证是正向的: "任务 1 完成了吗?任务 2 完成了吗?全部完成 = 目标达成。" 这隐含假设任务列表是完备的。
GSD 的目标回溯验证(Goal-Backward Verification)反转方向: "用户应该能做什么?这个能力在代码中存在吗?不仅存在,还是真实实现(非桩代码)?不仅实现了,还与系统连接了?"
四级验证层次:
1. Exists — 文件在预期路径
2. Substantive — 真实实现,非 TODO/placeholder
3. Wired — 与系统其他部分连接import 被使用API 被调用)
4. Functional — 实际调用时能工作
这对 AI 生成代码尤其重要: LLM 擅长生成"看起来正确"的代码(通过 Level 1-2但经常遗漏连接Level 3。GSD 的桩代码检测模式专门针对这一弱点。
