Daemon: OpenAI-compatible /v1/completions for Zed

Parses Qwen-format FIM prompts (prefix- or suffix-first, optional repo/file headers) back into
prefix/suffix and rebuilds them in the trained layout; mode from the model string (ac:symbols /
ac:simple); files located via workspaceRoots by path or content. extensions/zed/README.md documents
the Zed settings; untested against real Zed traffic yet.
