chore(coverage): relax thresholds to cut low-value churn
Lower the diff-coverage gate from 90% to 80% and the critical-module
target from 90% to 85%. The 90% diff gate forced back-fill tests on
nearly every changed line; 80% keeps new code honest without the churn.
Global coverage stays informational per ADR 0004 (no new gate added).

Updates scripts/diff_coverage.py, scripts/coverage.sh,
scripts/critical-modules.txt, .gitea/workflows/test.yml, and records the
change as a dated revision in ADR 0004.

# Combined unit + integration coverage (see docs/decisions/0004-coverage-policy.md).
#
# Two modes:
#
# scripts/coverage.sh [critical]
# Run mode (default, for local dev): executes the unit suite then the
# integration suite under coverage and prints a combined report.
#
# scripts/coverage.sh aggregate [critical]
# Aggregate mode (used by CI): combines pre-existing .coverage.* files
# produced by individual test jobs and prints a combined report. No tests
# are re-executed; no KVM or Docker dependency.
#
# Pass "critical" as the last argument in either mode to also report just the
# critical modules (ADR 0004 target: 85%).
