* feat(core): abstract runtime path logic for frozen distribution packages
* Address review feedback: revert browser MCP check, persistent data dir default when frozen, and add path tests
* refactor(constants): single source of truth for data dir + merge core/src constants

* docs(contributing): use named src.constants for data paths, drop core/constants references

Personal Docs (POST /api/personal/add_directory and friends) currently
returns HTTP 503 'RAG system is not available' for every request,
because get_rag_manager() and rag_manager are both hardcoded off. The
disablement was added when chromadb 1.4.1 / pydantic 2.12 were mutually
incompatible at the client init layer.
That compat issue is fixed in the current pins (chromadb 1.5.x +
pydantic 2.13.x). Verified by calling the original lazy initializer
against a running chroma server — VectorRAG instantiates, reports
healthy=True, and indexes successfully.
This change:
1. src/rag_singleton.py — replace the hardcoded `return None` in
get_rag_manager() with the original lazy init body. Keeps the
30s retry-throttle so a missing chroma server doesn't busy-retry
on every request.
2. app.py — replace the parallel `rag_manager = None` /
`rag_available = False` hardcoding with a get_rag_manager() call.
Logs the resolved state at startup. If chroma isn't reachable yet,
rag_manager stays None and personal-doc routes still return 503,
but the *next* request will hit the retry-throttle path in
get_rag_manager() and try to init again.
Doesn't touch requirements.txt. Repos using docker-compose get chroma
automatically; manual installs that want Personal Docs to work still
need to either pip install chromadb (full package) and run `chroma run`
or point at an external chroma instance via env. That can be a
follow-up README / requirements-optional note.
