Add repository refactor roadmap (rmap.md)

[ShakyPizza]

Motivation

• The codebase contains duplicated domain logic, monolithic orchestrators, and import-time side effects making a repo-wide rebase risky and costly.
• Provide a single, consumable roadmap that extracts key functions, highlights refactor targets, and proposes a migration-first file layout to reduce rebase conflicts.

Description

• Add a new root-level rmap.md that maps runtimes (Discord bot, GUI, FastAPI web), key modules (WOM.py, utils/*, weeklyupdater/*, web/*, gui.py), and the important functions to extract.
• Documented major pain points (duplication, global state, mixed concerns), a domain-first proposed file structure, a phased migration plan, and a short practical checklist to start the refactor.
• Recommend extraction priorities (rank service, CSV/JSON repositories, command modules, report helpers) and compatibility-first migration strategy to minimize merge/rebase friction.
• No runtime code behavior was changed; this is a planning/documentation-only addition.

Testing

• Ran the project's test suite with pytest -q from the repository root to validate repository state.
• Test run failed during collection because python/utils/baserow_connect.py raises a ValueError when the Baserow token is not set in python/config.ini, preventing tests from loading (ValueError: Baserow token is not set in the config.ini file.).
• No code changes were made to address the test failure in this PR; the failure is reported so the next refactor steps can add an import-time-safe Baserow client or test stubs before further test runs.
