hearth v0.8.0 - Projects

Project-aware agents. The new index_dir tool (and hearth_project module) walks a directory and ingests its code/text files into the knowledge base under name/relpath, skipping binaries and build dirs. Point an agent at a codebase, let it index, then kb_search to answer grounded in the real files. Docs: https://ericfinland.github.io/hearth/
