feat(git-hooks): implement conditional Husky activation system

- Implements conditional activation logic in husky.sh helper script
- Updates pre-commit hook to run linting only when enabled
- Updates commit-msg hook to validate messages only when enabled
- Adds .husky-enabled to .gitignore for user-specific activation
- Creates user activation instructions in .husky/README.md
- Provides graceful fallback when hooks are disabled

Activation: Environment variable, local file, or global config
Hooks: Pre-commit (linting) and commit-msg (validation)
Behavior: Optional activation with helpful instructions when disabled

+# Husky Git Hooks - Optional Activation
+
+## How to Enable Husky Locally
+
+### Option 1: Environment Variable (Session Only)
+```bash
+export HUSKY_ENABLED=1
+```
+
+### Option 2: Local File (Persistent)
+```bash
+touch .husky-enabled
+```
+
+### Option 3: Global Configuration
+```bash
+git config --global husky.enabled true
+```
+
+## Available Hooks
+
+- **pre-commit**: Runs `npm run lint-fix` before commits
+- **commit-msg**: Validates commit message format
+
+## Disable Hooks
+
+```bash
+unset HUSKY_ENABLED
+rm .husky-enabled
+```
+
+## Why This Approach?
+
+- Hooks are committed to git for consistency
+- Hooks don't run unless explicitly enabled
+- Each developer can choose to use them
+- No automatic activation on other systems
