Reach and enforce 100% aggregated branch coverage (#943)

The complete CI report now requires 100% line and branch coverage after
combining every Ruby version, platform, and shard. `AGENTS.md` documents
the same aggregate requirement.

Adds 69 regression examples covering hook parsers, Git failures and
state restoration, platform options, cached context values, and runner
interruptions. All existing tests are preserved. Simplifies redundant
guards that cannot take their alternate path, and stores the remote
history query in the cache that `PushedRef` already checks.

Validation:
- `bundle exec ruby script/parallel_rspec.rb`: 2,273 examples passed;
100% local line coverage. The only locally uncovered branch initializes
the Windows path separator and is exercised by Windows CI.
- `bundle exec overcommit --run`: passed.
- All 18 CI test jobs passed across Ruby 3.3, 3.4, and 4.0 on Linux and
Windows; CI lint and CodeQL passed.
- The CI aggregate gate and an independent check of all 18 downloaded
reports both confirmed **100% line coverage (3,841/3,841)** and **100%
branch coverage (1,064/1,064)**.
