Add TrackFlow to the list of ActivityWatch forks

[CODEX-cpp]

Adds TrackFlow to the "Examples of forks" list in forking.rst, as requested there ("If you fork ActivityWatch, please add your fork to this list.").

TrackFlow is a Windows desktop fork rewritten in Rust/Tauri: a single in-process server with no open network port, a redesigned UI, project/stopwatch tracking, category tagging, custom notifications, and an extensible custom-watcher system for tracking arbitrary data sources.

It follows the forking requirements described on this same page: its own name and logo, no affiliation with the main ActivityWatch project, same license (MPL-2.0), public source code.

Greptile Summary

Adds TrackFlow to the documented examples of ActivityWatch forks.

• Links to the TrackFlow GitHub repository using the existing Sphinx gh role.
• Summarizes the fork’s Windows, Rust/Tauri, tracking, notification, and extensibility features.

Confidence Score: 5/5

The documentation-only change appears safe to merge.

The new entry follows the existing reStructuredText list and GitHub-role syntax, with no build, behavioral, or security failure identified.
