VSC: Extension auto-detects + spawns server

[Hmbown]

Summary

Extension finds the deepseek binary on PATH; if missing, prompts to install via brew/cargo/npm; otherwise spawns deepseek serve --http --port 0 and reads the chosen port from stdout.

Acceptance criteria

• First-run experience handles installed and not-installed states.
• Port is per-workspace.
• Server is killed on extension deactivate.

Source tag: VSC. Add exact upstream/opencode source links during implementation if they are not already known. Do not copy external code blindly; port the behavior into this repo's architecture.
