docs: update all tool descriptions in README, llms.txt, llms-full.txt

Synchronized tool descriptions across all documentation:
- README.md: Available Tools table
- llms.txt: 9 MCP Tools list
- llms-full.txt: 3 tool lists updated

Key improvements:
- search_code: "Use FIRST", Go/PHP/Python support
- hybrid_search: "EXACT matches" emphasis
- get_function_details: "COMPLETE" code
- find_implementations: "use before refactoring"
- search_docs: "Not for code" clarification
- index_workspace: "Usually automatic"
