Real-world reports: stalling/choking under ~10% throttle and while
blipping the throttle at low speed, after snorkel removal with no
main-table correction for the extra airflow. Confirmed via a genuine
percentage-delta pulled from 20184dynoTuneSteveO2-Disable.hex (also
snorkel-removed) vs its own stock baseline 20186Map.hex, in the
Low-throttle fuel tables, restricted to the throttle columns actually
implicated (raw throttle <= 100, ~10%).
compose_lowthrottle.py composes onto the already-composed
20262-arrow-delete-composed.hex (not raw stock 20262) -- additive on top
of the existing SAI/O2-off + idle-trim layer, same "respect what's
already there" principle as compose_arrow_delete.py. Percentage-based
per-cell, not flat additive, since Arrow's own table already has its own
exhaust-specific correction baked in.
Output: derived/20262-arrow-delete-lowthrottle-composed.hex. Checksum
patched and verified valid; confirmed layer-1's device flags and trim
bytes survive unchanged underneath.

The composed .hex files were missing a valid flash checksum entirely
(checksum.py flagged MISMATCH on both) -- not flash-ready as committed.
Patches the checksum in-place for both, and fixes compose_arrow_delete.py
to patch it automatically on future regenerations instead of leaving it
as a manual follow-up step.

Removes the *.hex/maps_cache gitignore rule (explicit user call, reversing
the earlier no-redistribution stance) so the official TuneECU catalogue
maps, derived SAI/O2-delete composites, and the checksum/composition
tooling are actually available to pull up on a phone browser when using
the real TuneECU app. Also folds in tonight's KWP2000 fixes (TesterPresent
keep-alive, connect-failure cleanup, slow-init StartCommunication fix) and
the accumulated research docs.
