Casually9790andClaude Opus 5.5 e00f40eaf4 Split ctf_status.py into a tracker package, config from .env only
ctf_status.py is now just the command line; the work lives in tracker/.
The rules that decide whether a challenge is believed are in
tracker/checks.py, one function per rule, listed in README_CHECKS and
REPO_CHECKS. Output is unchanged.

Read the config from .env only (ctf_status.env.example -> .env.example),
let single_run_lock() hold its own lock files, and rewrite the README as
a short overview of what the repo does and how to run it.
