docs: add KARDS ToS disclaimer and trademark notice

[AABur]

Summary

• Add a ## Disclaimer section to README.md clarifying that kardscm is an unofficial fan tool, intended for personal non-commercial use, and that users are responsible for complying with the KARDS Terms of Use — in particular §6 and §7 on scraping and systematic data compilation.
• Note that the repo ships no card data, art, or pre-built database — the local SQLite catalog is built on the user's own machine.
• Cross-link the disclaimer from the ## License section so the MIT license is not mistaken for granting rights over KARDS game content.

Why

README.md previously advertised catalog sync, exports, and API baseline drift tracking with no acknowledgement of 1939 Games' trademarks or the ToS restrictions. This adds the missing legal framing while keeping all functionality intact.

Test plan

• grep -i "terms of use\|1939 games\|disclaimer" README.md finds the new section and link
• git diff --stat shows only README.md changed (1 file, +26/-1)
• Visual check of the rendered Markdown on the GitHub PR page

Pull request overview

Adds legal/ToS framing to the project README so the tool’s MIT-licensed source code isn’t mistaken as granting rights over KARDS game content, and clarifies intended use and user responsibility.

Changes:

• Adds a new Disclaimer section describing unofficial status, trademark ownership, and ToS compliance expectations.
• Clarifies that the repo ships no card data/art/prebuilt DB and that the local catalog is built on the user’s machine.
• Expands the License section to distinguish code licensing (MIT) from KARDS content/trademark rights and points readers to the Disclaimer.

Fixed in 91cc76c — Disclaimer is now [Disclaimer](#disclaimer), a proper anchor link readers can click through to reach the section directly.

Done in 8b5d80a. Removed the bullet list with explicit §6/§7 references, redistribution warnings, and the maintainer compliance note. The disclaimer now fits in three short paragraphs: unofficial status + trademark, personal use + ToS link, no shipped data.
