Bumps Director to 0.13.0, the first public release. Merging this publishes the GitHub Release with Director-x64-setup.exe from the main build, as the workflow does for every version increase.

Changelog entry:

• Open source under the MIT License; the installer ships LICENSE.txt and the third-party notices.
• Every settings file starts at format version 1; files from earlier previews aren't read.
• display presets / display current are gone (use display list / display screens).
• New README with highlights, a screenshot slideshow and Stream Deck examples; guides merged into fewer pages.

Verified: cargo check, a release build reporting Director 0.13.0, and the refreshed Cargo.lock entry.
