fix: #1430 - Prevent shell injection in commit messages

- Add safe_commit.py tool for safe commit message handling
- Add commit-msg hook to warn about dangerous patterns
- Add documentation for safe commit practices
- Prevent shell injection from backticks and other special chars

Addresses issue #1430: [IMPROVEMENT] memory_mine.py ran during git commit

Problem: Commit messages containing backticks can trigger shell execution.
Solution: Use git commit -F <file> or escape special characters.

Tools added:
- bin/safe_commit.py: Safe commit tool with escaping and file-based commits
- .githooks/commit-msg: Hook to warn about dangerous patterns
- docs/safe-commit-practices.md: Documentation for safe commit practices

Example safe usage:
  python3 bin/safe_commit.py -m "Message with backticks: \`code\`"
  git commit -F <file>  # Safest method
  git commit -m "Message with escaped backticks: \`code\`"

This prevents unintended code execution during git operations.

+# Safe Commit Practices
+
+**Issue:** #1430 - [IMPROVEMENT] memory_mine.py ran during git commit — shell injection from commit message
+
+## Problem
+
+During commit for #1124, the commit message contained Python code examples that triggered shell execution of memory_mine.py. The backtick-wrapped code in the commit message was interpreted by the shell during git commit processing.
+
+This is a potential vector for unintended code execution.
+
+## Safe Commit Methods
+
+### 1. Use `git commit -F <file>` (Recommended)
+
+The safest way to commit messages containing code or special characters:
+
+```bash
+# Create a file with your commit message
+echo "Fix: implement memory_mine.py with backtick example
+
+Example: \`python3 bin/memory_mine.py --days 7\`
+
+This commit adds memory mining functionality." > /tmp/commit-msg.txt
+
+# Commit using the file
+git commit -F /tmp/commit-msg.txt
+```
+
+### 2. Use the Safe Commit Tool
+
+```bash
+# Safe commit with automatic escaping
+python3 bin/safe_commit.py -m "Fix: implement memory_mine.py with backtick example"
+
+# Safe commit using file
+python3 bin/safe_commit.py -F /tmp/commit-msg.txt
+
+# Check if a message is safe
+python3 bin/safe_commit.py --check -m "Example: \`python3 bin/memory_mine.py\`"
+```
+
+### 3. Escape Shell Characters Manually
+
+If you must use `git commit -m`, escape special characters:
+
+```bash
+# Escape backticks and other shell characters
+git commit -m "Fix: implement memory_mine.py with backtick example
+
+Example: \\`python3 bin/memory_mine.py --days 7\\`
+
+This commit adds memory mining functionality."
+```
+
+## Dangerous Patterns to Avoid
+
+The following patterns in commit messages can trigger shell execution:
+
+- **Backticks**: `` `command` `` → Executes command
+- **Command substitution**: `$(command)` → Executes command
+- **Variable expansion**: `${variable}` → Expands variable
+- **Pipes**: `command1 | command2` → Pipes output
+- **Operators**: `&&`, `||`, `;` → Command chaining
+- **Redirects**: `>`, `<` → File operations
+
+## Installation
+
+### Install the Commit Hook
+
+To automatically warn about dangerous patterns:
+
+```bash
+# Install the commit-msg hook
+python3 bin/safe_commit.py --install-hook
+
+# Or manually
+cp .githooks/commit-msg .git/hooks/commit-msg
+chmod +x .git/hooks/commit-msg
+```
+
+### Configure Git Hooks Path
+
+If using the `.githooks` directory:
+
+```bash
+git config core.hooksPath .githooks
+```
+
+## Examples
+
+### ❌ Dangerous (Don't do this)
+
+```bash
+# This could trigger shell execution
+git commit -m "Fix: implement memory_mine.py
+
+Example: \`python3 bin/memory_mine.py --days 7\`
+
+This mines sessions into MemPalace."
+```
+
+### ✅ Safe (Do this instead)
+
+```bash
+# Method 1: Use file
+echo "Fix: implement memory_mine.py
+
+Example: \`python3 bin/memory_mine.py --days 7\`
+
+This mines sessions into MemPalace." > /tmp/commit-msg.txt
+git commit -F /tmp/commit-msg.txt
+
+# Method 2: Use safe commit tool
+python3 bin/safe_commit.py -m "Fix: implement memory_mine.py
+
+Example: \`python3 bin/memory_mine.py --days 7\`
+
+This mines sessions into MemPalace."
+
+# Method 3: Escape manually
+git commit -m "Fix: implement memory_mine.py
+
+Example: \\`python3 bin/memory_mine.py --days 7\\`
+
+This mines sessions into MemPalace."
+```
+
+## What Happened in Issue #1430
+
+During commit for #1124, a commit message contained:
+```
+Example: \`python3 bin/memory_mine.py --days 7\`
+```
+
+The backticks were interpreted by the shell during git commit processing, causing memory_mine.py to execute. While the outcome was positive (26 sessions mined), this is a security risk.
+
+## Prevention
+
+1. **Always use `git commit -F <file>`** for messages containing code
+2. **Install the commit-msg hook** to warn about dangerous patterns
+3. **Use the safe_commit.py tool** for automatic escaping
+4. **Document safe patterns** in team guidelines
+
+## Related Issues

+- **Issue #1124:** Original issue that triggered the problem

+
+## Conclusion
+
+Shell injection in commit messages is a real security risk. By using safe commit practices, we can prevent unintended code execution while still allowing code examples in commit messages.
+
+**Remember:** When in doubt, use `git commit -F <file>` instead of `git commit -m`.
