catarrh 71d2e80242 C-APDU parser: P1/P2 descriptors, INSTALL LV decode, structural fixes; v1.9.1 
Parser labels (§8.3, verified against GPC v2.3 / TS 102 221 PDFs):
- describeP1P2: SELECT P1/P2 (FID/DF-name/path-MF/path-DF; FCP/no-data),
  READ/UPDATE RECORD modes (next/previous/absolute + SFI, P1-ignored note),
  GET STATUS P1 (ISD/Apps/ELF/ELF+Modules) and P2 formats,
  INSTALL P1 bit-aware roles ('for install + for make selectable'),
  SET STATUS P1 (80 ISD / 40 App-or-SSD / 60 SD+associated) with
  card states vs lock/unlock P2, VERIFY/CHANGE PIN ref

Parser structure (§8.4):
- describeInstallDataLv: exact-sum LV walker for all 5 INSTALL layouts
  with privilege bit names and params tag nesting (C9, EF->CA, EA->80);
  falls back to legacy TLV view when lengths do not sum exactly
- GET DATA: case-2 (P3=Le) vs case-4 (Lc + tag list + Le)
- SET STATUS data: 'ignored for ISD' / raw AID / legacy 4F-TLV labeled
- Trailing single byte consumed as Le at end of compact chain
- ACTIVATE/DEACTIVATE: case-1 (4 bytes), legacy empty-Lc, FID/path forms
- Expanded script C-APDU rows now decode into structured APDU nodes
- Compact matcher accepts CLA 84-87 (GP secure messaging)
