feat: 207× throughput multiple (with private repos + Bookface)

Re-ran scripts/garry-output-comparison.ts across all 41 repos under
garrytan/* (15 public + 26 private), including Bookface (YC's internal
social network, 2013-era work).

2013 activity: 71 commits, 5,143 logical lines, 4 active repos
  (bookface, delicounter, tandong, zurb-foundation-wysihtml5)
2026 activity: 350 commits, 1,064,818 logical lines, 15 active repos
  (gbrain, gstack, gbrowser, tax-app, kumo, tenjin, autoemail, kitsune,
  easy-chromium-compiles, conductor-playground, garryslist-agent, baku,
  gstack-website, resend_robot, garryslist-brain)

Multiples:
- Logical SLOC: 207× (up from 130.2× when including private work)
- Raw lines: 223×
- Commits/active-week: 3.4×

Stopped committing docs/throughput-2013-vs-2026.json — analysis is a
local artifact, not repo state. Added docs/throughput-*.json to
.gitignore. Full markdown analysis at ~/throughput-analysis-2026-04-18.md
(local-only). README multiple is now hardcoded; re-run the script and
edit manually when you want to refresh it.

 I'm [Garry Tan](https://x.com/garrytan), President & CEO of [Y Combinator](https://www.ycombinator.com/). I've worked with thousands of startups — Coinbase, Instacart, Rippling — when they were one or two people in a garage. Before YC, I was one of the first eng/PM/designers at Palantir, cofounded Posterous (sold to Twitter), and built Bookface, YC's internal social network.
 
-**gstack is my answer.** I've been building products for twenty years, and right now I'm shipping more products than I ever have. In the last 60 days: 3 production services, 40+ shipped features, part-time, while running YC full-time. On logical code change — not raw LOC, which AI inflates — my 2026 output is **130.2×** <!-- GSTACK-THROUGHPUT-PLACEHOLDER --> my 2013 output pro-rata. (Public repos only; private work at both eras is excluded to make the comparison apples-to-apples.) AI wrote most of it. The point isn't who typed it, it's what shipped.
