Playwright browser tooling, bash tool improvements, and browser stability fixes

Adds Playwright MCP browser tooling for agents, improves the bash tool output format, removes MLX/vllm-mlx integration, and ships a series of browser worker stability and transport fixes.

Features

Playwright MCP browser tooling — agents can now control a real browser via the new Playwright MCP sidecar (AUX-121). Each worker shares a single Chrome process, with session lifecycle managed over Streamable HTTP MCP transport.
Structured bash tool output — the bash tool now returns a JSON object with stdout, stderr, output, and status fields instead of a raw string, making it easier for agents to inspect command results programmatically.

Fixes

Fixed stale snapshots in the browser worker by patching playwright-core’s waitForCompletion logic.
Fixed non-isolated browser mode and ensured DELETE /mcp is called correctly on session close.
Rewrote session.go to properly implement the Streamable HTTP MCP transport, resolving connection and lifecycle issues.
Switched the Playwright MCP sidecar to a real Node.js 22 runtime, fixing compatibility issues with playwright-mcp.

Internal

Removed MLX and vllm-mlx local model integrations; hardened llama.cpp streaming for stability.
Full browser worker test suite now passing across isolated and shared-Chrome modes.
