Feature Request: Learn from `zvec-grep`

[reneleonhardt]

What problem does this solve?
Could codemap learn from https://github.com/zvec-ai/zvec-grep/blob/main/docs/02-cli.md strengths and features?

Proposed solution
Could an in-process vector database like https://github.com/alibaba/zvec help searching smarter?

Implemented in a secure way of course:

Why zg?

• Search beyond keywords — discover by meaning, rank by relevance, then
  verify with exact text or regex when needed.
• Multi-format search — search source code, documents, and structured data
  while preserving useful structure and source locations.
• Less searching, less context — ranked, source-linked results surface the
  right evidence with fewer tool calls, fewer tokens, and less noise.
