refactor(@angular/cli): remove granular build, test, and e2e MCP tools

Remove build, test, and e2e standalone tool declarations from the MCP server registry. Now that the unified run_target Strategy Dispatcher facade is fully operational and verified, these granular tools are redundant. Removing them reduces system prompt context footprint by over 1,000 tokens, eliminates semantic clashing, and increases tool selection accuracy for client LLMs.

(cherry picked from commit 377540d)
