Consolidate MCP server: remove voice bridge, add schedule/terminal/worktree tools

Merge agent-management and agent MCP into a unified server with shared
utilities. Remove the voice-mcp-bridge in favor of direct MCP tool
registration. Add schedule, terminal, and worktree management tools to
the MCP server for CLI parity. Include e2e parity tests.
