docs: fix markdown formatting and improve git hook security

- Fix markdown list spacing (MD030) in performance, audit logs, and CSP docs
- Remove ineffective while loop in commit-msg hook that caused subshell issues
- Improve fetchWithRetry function with proper retry limits and exponential backoff
- Update CSP metrics retention documentation for consistency

## Index Strategy Principles
### 1. Composite Index Design
- **Leading column**: Most selective filter (usually companyId for multi-tenancy)
- **Secondary columns**: Common WHERE clause filters
- **Covering columns**: SELECT list columns via INCLUDE

### 2. Partial Indexes
- Used for error analysis and specific status filtering
- Reduces index size and maintenance overhead
