The "consider bumping" hint pointed to `coverage/floor.txt`, but the floor moved to `pubspec.yaml`'s `coverage_floor:` key when the gate was first folded together. Updates the message to match the actual source. Co-Authored-By: Claude <noreply@anthropic.com>

# Coverage gate — fails if total line coverage drops below the
|
|
# `coverage_floor:` value in pubspec.yaml. Driven by D-66.

# Reads coverage/lcov.info (generated by `flutter test --coverage`,
|
|
# which `ci/test.sh` runs as part of the fast suite). Parses the
|
|
# total LF/LH counts and compares the integer percentage against
|
|
# the floor. The floor only ratchets up — bumping it requires an
|
|
# explicit edit to pubspec.yaml committed alongside the test
|
|
# additions that earned the bump.
|
|
#
|
|
# Self-contained parser (awk) — does not depend on `lcov` being
|
|
# installed on the dev machine.
