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.

docs/CONTEXT.md captures the entire reverse-engineering effort in one place:
KWP2000 protocol, AES-128 seed/key, the map format (dc decrypt -> flat-ROM
unpack -> directory -> fe table pointers), the fuel/ignition table map, the
validated SAI/O2 device flags, checksums, hardware, and a per-finding confidence
table.
docs/ROADMAP.md covers open-sourcing (legal/IP posture on proprietary maps and
the AES keys, repo hygiene, packaging/CI, community) and the technical path to
tuning the bike (first contact -> ROM dump -> calibration model -> write path ->
editor), with immediate next steps and a risk register.
Top-level README refreshed to describe the whole project (tool + viewer +
research) and point at docs/.
