Clean up and restructure JavaScript REPL description following consistent pattern: - Purpose section - When to Use section - Environment section - Common Libraries section - Important Notes section - Example section Removed buildJavaScriptReplDescription() function - no longer dynamically injecting runtime provider docs into tool description (will move to system prompt). Changes: - Replace JAVASCRIPT_REPL_BASE_DESCRIPTION with JAVASCRIPT_REPL_DESCRIPTION - Remove JAVASCRIPT_REPL_CHART_EXAMPLE and JAVASCRIPT_REPL_FOOTER - Remove buildJavaScriptReplDescription() function - Update javascript-repl tool to use static description - Simpler, more scannable structure with clear hierarchy
