Hex Documentation Search

Search Elixir package documentation. Prioritize local sources, fetch if needed.

Search Locations (in order)

1. Project deps: deps/<package>/lib/ (source with @moduledoc/@doc), deps/<package>/doc/ (HTML if generated)
2. Fetched docs cache: .hex-docs/docs/hexpm/<package>/<version>/
3. Fetched source cache: .hex-packages/<package>-<version>/
4. HexDocs API: Programmatic search (see below)
5. Web search: Last resort with site:hexdocs.pm

Fetching Locally

Determine version from mix.lock, mix.exs, or prompt user if ambiguous.

# Fetch documentation (stores in .hex-docs/)
