Matthew Stanley e88e9a0233 phase 4: fix mc_flag persistence so multi-sector card reads work
Before: only sector 0 read succeeded; sector ≥1 reads aborted at 2 bytes
because mc_flag was loaded from mc_slots[].flag on every 0x81 select but
never saved back. The clear in MC_CMD lived only in the working static, so
every reselect re-loaded the stale 0x08 ("new card / changed battery") init
value, and the BIOS bailed every multi-sector op as "card was just inserted,
re-init."

After: BIOS shell memcard menu reads the full 15-sector directory area for
both slots. Real save filenames decode (e.g. "BISLPS-01234SAVE00") and per
card icons render in the bottom panes — the Phase 4 success criterion.

Also bundled this session:
- debug_server: B9D0..B9F0 added to always-on wtrace ranges; fn_dump_parse
  default window scoped to 1M most-recent entries (filter scans against the
  full 128M ring used to freeze the debug server thread for many seconds).
- ISSUES.md + diagnostic tools/*.py written during the audit.
