framework tools/git: issue-edit R1/R4 conversion (P1)

issue-edit already used long-flag-first parsing; this adds the rc=2
usage-error contract (unknown option, missing -i, value-less flags
across all five options), the exit-code line in help, and the enrolled
usage-contract suite (population 78). Mirrored to the brain tree.

# Usage-error contract for issue-edit.sh (R4, 2026-08-28).
#
# issue-edit already uses long-flag-first parsing (-i/--issue, -t/--title,
# -b/--body, -l/--labels, -m/--milestone); this adds the rc=2 usage-error
# contract, value checks, and the no-provider-contact proof. Required: -i.
#
# Arms:
# 1. --help and -h exit 0 and print usage.
# 2. Unknown option exits 2 with the message on stderr.
# 3. Missing required -i exits 2 (stderr).
# 4. A value-less flag (-i -b -c and long forms) exits 2 (stderr).
# 5. -b and -c both pass parsing (sandboxed runner: the run then fails
# at credential resolution, nonzero and NOT 2) — no real token is
# ever read and no provider is contacted.
# 6. No arm performs any provider request (PATH shims record every
# invocation; the probe log must stay empty).
