Unix socket IPC mechanism in the Chrome CDP skill for sandboxed environments.

Technical Positioning
Ensuring the Chrome CDP skill functions reliably in sandboxed environments by redesigning its IPC mechanism to bypass `EPERM` errors associated with Unix domain sockets, thereby enabling all page-level commands for enterprise and cloud users.
SaaS Insight & Market Implications
The Chrome CDP skill is unusable in sandboxed environments due to Unix socket IPC failures (`EPERM`), blocking all page-level commands. The daemon's reliance on `/tmp/cdp-.sock` for IPC is incompatible with common enterprise and cloud-hosted setups that restrict `AF_UNIX` syscalls. This represents a critical architectural flaw, severely limiting the skill's market applicability. For B2B SaaS, sandboxing is a standard security and deployment practice. A tool that fails in such environments is fundamentally broken for a large segment of the target market. A robust solution requires an alternative IPC mechanism that respects sandboxing constraints, ensuring core functionality for enterprise users.

Unix socket IPC fails with EPERM in sandboxed environments, blocking all page-level actions

## Problem

When running the chrome-cdp skill in a sandboxed environment (common in enterprise deployments, containerized setups, and cloud-hosted AI coding tools like Claude Code on the web), **all page-level commands fail** because the per-tab daemon cannot create its Unix domain socket.

The daemon uses Unix sockets at `/tmp/cdp-.sock` for IPC between the CLI and the persistent CDP connection. Sandboxed environments block the `socket()` / `bind()` syscalls for `AF_UNIX` at the kernel level, producing:

Error: listen EPERM: operation not permitted /tmp/cdp-XXXXXXXXXX.sock

This means none of the following commands work in a sandboxed environment:
- `snap` / `shot` / `html` — cannot take page snapshots or screenshots
- `eval` — cannot evaluate JavaScript on the page
- `nav` / `click` / `type` — cannot navigate or interact with page elements
- `net` — cannot capture network requests
- `loadall` — cannot inject lazy-loaded content

Only `list` partially works (when it falls through to a direct WebSocket connection), but any command that requires a daemon — which is all per-tab commands — fails immediately.

## Impact

This effectively makes the skill **unusable in any sandboxed environment**. Since sandboxing is increasingly common in enterprise settings (Docker containers, cloud workspaces, managed developer environments), this is a significant limitation that blocks a large class of users from using the skill at all.

## Root Cause

The daemon in `cdp.mjs` calls `s...
