Repo audit pass: hardening, hygiene, virality

install.sh:
- Atomic download (.tmp + mv), curl --retry 3 --proto =https
- Backup existing target as .bak.<ts> before overwrite; skip with UNCHANGED if identical
- Guard LOCAL_PROMPT under curl|bash (BASH_SOURCE may be empty)
- Fix verify_hermes grep to ^# TLDR (matches all variants)
- Canonical repo URL jqbit/TLDR (was rename-alias jqbit/TLDR.md)

README.md:
- Add license / stars / last-commit badges
- Hoist -82% headline result above the fold with footnote
- Add Install-arg column to variants table; recommend TLDR.merged.md
- Add inspect-first one-liner + star CTA
- Demote benchmark caveat to a footnote, lead with results
- Align Hermes verify grep with script
- Canonical URLs

CONTRIBUTING.md:
- Add accurate + merged variants to bullets, CI dry-run examples

data/agent-locations.md:
- Variants blockquote covers all 4; "Most people: merged" hint
- Canonical URLs; align Hermes verify grep

data/contributing.md: removed (duplicate of root CONTRIBUTING.md)

New files:
- .gitignore: macOS/editor/python/node noise + *.bak.*
- SECURITY.md: advisory link + curl-pipe-bash scope note

Historical bench/research/philosophy docs untouched.

 TLDR.md makes AI assistants answer directly: less filler, less fake enthusiasm, less "let me know if..." sludge.
 
 > It changes communication style only.
 > Tools, reasoning, code quality, and safety stay the same.
