Surface the metric ADR 0004 says matters — the critical security/logic
core, currently 95% — as a README badge, distinct from the
informational global `coverage` badge.
- scripts/critical-modules.txt: single source of truth for the core
module list. scripts/coverage.sh now reads it (instead of a hardcoded
string) and update-badges.yml reads the same file, so the badge and
the `critical` report cannot drift.
- update-badges.yml: a `core coverage` step reuses the unit-coverage
data (every core module is unit-tested, so unit-only is accurate for
it) and sed-updates the new badge, like the existing ones.
- README: `core coverage 95%` badge linking to ADR 0004 so a reader can
find out what "core" means.

Adopt ADR 0004: stop chasing a single global coverage number and
measure what matters instead.
- Omit the genuinely-interactive `cli/init.py` shell (read_tty_line
prompt loops) alongside the existing `cli/tui.py`, with a rationale
comment in .coveragerc. Subprocess/backend orchestration is NOT
omitted — it stays visible and is scored via the integration suite.
- scripts/coverage.sh runs unit + integration under one coverage
measurement (the policy's yardstick) and can report the critical
security/logic core held to the >=90% target.
- scripts/diff_coverage.py is a stdlib-only gate (no diff-cover dep):
new/changed executable lines must be >=90% covered. This is the
enforced regression guard; the global number is informational.
- CI gains a `coverage` job: combined report + the diff-coverage gate.
- Unit-test `cli/__init__.py` dispatch/exit-code mapping (it's logic,
not I/O, so it earns tests rather than an omit).
Combined unit+integration coverage now reports 83% global / 87% across
the critical modules; per-module ratcheting toward 90% is the ongoing
work this policy frames.
