Backfill memory files for all existing scripts and skills

Creates MEMORY.md index and 10 memory files documenting:
- Scripts: context-load, start-claude, install-hooks, setup-formatters, git-status-report
- Skills: /log, /reflect-logs, /reflect, /distill-best-practices, /linter

Each file covers purpose, usage, how it works, and gotchas.

+## Scripts
+
+- [context-load](memory/script-context-load.md) — Walks cwd upward collecting CLAUDE.md, CONTEXT.md, MEMORY.md, BESTPRACTICES.md, trees, and git status for system prompt injection
+- [start-claude](memory/script-start-claude.md) — Wrapper that runs context-load and launches claude with --append-system-prompt
+- [install-hooks](memory/script-install-hooks.md) — Symlinks hooks into ~/.claude/hooks/ and prints settings.json config
+- [setup-formatters](memory/script-setup-formatters.md) — Opts a project into auto-formatting by symlinking formatter scripts
+- [git-status-report](memory/script-git-status-report.md) — Scans directories for git repos, reports uncommitted changes and remote sync (lives in small-scripts)
+
+## Skills
+
+- [/log](memory/skill-log.md) — End-of-session logging to memory/log/ for later reflection
+- [/reflect-logs](memory/skill-reflect-logs.md) — Processes session logs into topic memory files (gotchas, decisions, process lessons)
+- [/reflect](memory/skill-reflect.md) — Milestone reflection: reviews conversation + git log, produces structured artifacts
+- [/distill-best-practices](memory/skill-distill-best-practices.md) — Cross-project distillation of memory files into best-practices/ topic files
+- [/linter](memory/skill-linter.md) — Audit and manage project formatters/linters (scan, run, cleanup modes)
