docs: v3.27.1 — fact-check corrections, grepai docs, RTK overhaul

Fact-check (README positioning):
- Template count: 120/123 → 108 (ground truth recount)
- Ratio: 14× → 24× (19,000 ÷ 784 = 24.2×)
- everything-cc stars: 31.9k → 45k+ (verified Feb 15)
- Commands count: 20 → 23, hooks: 30 → 31

Added:
- Grepai MCP documentation (semantic search, call graphs)
- 3 hook templates (rtk-baseline, session-summary, session-summary-config)
- 2 resource evaluations (system-prompts update, qmd token savings)

Changed:
- RTK documentation overhaul (v0.7.0 → v0.16.0, rtk-ai org)
- Exports deprecated (kimi.pdf, notebooklm.pdf → deprecated/)
