Rename MCP server tool name: database_* to rtdb_*

[google-labs-jules]

This change renames the MCP server tool name from database_* to rtdb_*.

Specifically, the following tools have been renamed:

• database_get_data -> rtdb_get_data
• database_set_data -> rtdb_set_data
• database_get_rules -> rtdb_get_rules
• database_validate_rules -> rtdb_validate_rules

The directory src/mcp/tools/database has been renamed to src/mcp/tools/rtdb.
The feature name has been changed from database to rtdb in src/mcp/types.ts, src/mcp/prompts/index.ts, and src/mcp/util.ts.
The README.md has been updated to reflect the new tool names and the new feature group name (rtdb).
