Docs: reflect this session's findings across the repo
- top-level README.md (new): system overview, subsystem map, skills pointer,
notable findings.
- eg4battery README/NOTES: 3 -> 6 packs (pack 6 oddball 0x01/115200); SoC drift
+ calibration section; closed-loop comms evaluated and rejected (loses per-pack
telemetry, no native protocol, doesn't fix drift); how to force a grid charge
via output-priority SUB.
- LVX6048 README: closed-loop pending item -> resolved decision; new "SoC
calibration & known firmware quirks" section (POP single-digit/POP01, MCHGC
charge-lock, re_discharge=re-discharge can't exceed float, PIRI lag, powermon
adhoc wedge); skills pointer.
- lvx-control README: POP encoding fix, POP crc-but-applies quirk, verify-by-
behavior, grid-charge-via-SUB usage.
- troubleshoot-inverter skill: corrected the stale "dead string per inverter"
claim — both strings healthy; low PV is tilt/heat/shade/curtailment.
