@laurimyllari noted in disc #62 that with the project moving fast,
including the club-3090 git commit in sweep output helps correlate
cross-rig sweeps to the script revision they were run against. He
stamped `aa99173` manually; the script should do it for us.
New flag:
--include-commit Stamp the club-3090 git commit (short SHA) in the
report header next to the date. Off by default.
Implementation:
- Captures `git -C "$REPO_ROOT" rev-parse --short HEAD` once at header-build
time (REPO_ROOT was already known to the script).
- Injects into the report header next to **Date:**, e.g.:
**Date:** 2026-05-10T17:55:00Z **club-3090 commit:** `534d29f`
- Suppress (don't stamp "n/a") when run from a non-clone or git is
unreachable. Closes the curl-pipe-from-docs UX hole — `curl ... | bash`
users don't have a clone, so the field just disappears rather than
showing a confusing "n/a".
Off by default per the issue rationale: surprise stamping confuses
contributors running from documentation snippets.
Closes#112.
