Pull request overview

This PR adds a debug-only “VS Code Connection Bridge” to the plugin, exposing a JSON-RPC API over a deterministic named pipe (Windows) / Unix domain socket (macOS/Linux) so a VS Code extension can discover the running plugin and render an action tree view without a port handshake.

Changes:

• Start a bridge adapter during streamDeck.connect() (debug mode only) to serve plugin snapshots and accept settings updates via JSON-RPC.
• Add a deterministic pipe-path derivation plus a socket server transport (named pipe / UDS) for local VS Code connectivity.
• Add Vitest coverage for the adapter and socket transport, plus mocks and a minor .gitignore update.
