fix: correct malformed .gitignore Cargo.lock entry

[Kingvic300]

Summary

The last line of .gitignore was Cargo.lock (shared) — not a comment (comments need a leading #). Git interpreted it as a pattern matching a file literally named Cargo.lock (shared); it did not ignore Cargo.lock (which is correctly committed for a binary workspace), and the trailing text was misleading.

Changes

• Replace the line with a proper comment in .gitignore explaining why Cargo.lock is tracked.

Closes #44

Poem

In .gitignore sat a line most malformed,
Cargo.lock (shared) — a pattern that stormed,
Git read it as literal, pattern askew,
A comment now clears what was false into true. 📝✨
