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.

+# script: git-status-report
+
+**Location:** `~/dev/claude/small-scripts/scripts/git-status-report`
+**Symlinked to:** `~/sbin/git-status-report`
+**Source project:** small-scripts (not claude-foundations)
+
+## Purpose
+
+Recursively scans a directory for git repos and reports uncommitted changes and remote sync status. Used by `context-load` to include git status in the system prompt.
+
+## Usage
+
+```bash
+git-status-report [OPTIONS] [DIRECTORY]
+```
+
+- `-n, --dryrun` — List discovered repos without running status checks
+- Default directory: cwd
+
+## How it works
+
+1. **Discovery:** Finds all `.git` directories, filters out nested repos
+2. **Status:** For each repo, runs `git status --porcelain` and checks remote tracking branches
+3. **Character diff:** Reports approximate character-level additions/removals per file (not just line counts)
+4. **Report:** Prints dirty repos with colour-coded status, clean repo count at the end
+
+## Gotchas
+
+- Does not `git fetch` — reports against local tracking refs only (speed over accuracy)
+- Exit code 1 if any repo is dirty (useful for CI/scripting)
+- ANSI colour output — `context-load` strips it via `strip_ansi` when embedding in system prompts
