First child of T-89. Codifies "don't make coverage worse" as a
durable pre-push contract before any test-writing children land.
- pubspec.yaml: new `coverage_floor: 34` key. Single source of
truth for the floor; ratchets up only.
- ci/coverage_gate.sh: parses coverage/lcov.info (LH/LF), reads
the floor from pubspec.yaml, exits non-zero if integer-truncated
measured % drops below it. Self-contained awk parser — no `lcov`
CLI dependency.
- ci/test.sh: flutter test now runs with --coverage, so the gate
reads fresh data without an extra test invocation. Wall time
delta is small and stays inside the < 90 s pre-push budget
(D-29).
- Makefile: new `coverage-gate` target wires the script in;
`push-check` adds it as a dependency. The .githooks/pre-push
hook (already wired) picks this up automatically.
- .gitignore: ignore /coverage/ wholesale; the floor lives in
pubspec.yaml, nothing under coverage/ is committed.
Decision recorded as D-66 (decisions/testing.md). End target is
95%; reaching it is tracked as the rest of T-89's children.
