feat(rawcli): command catalogs + hints for identified LF chips

catalog_for() returned None for LF, so after identifying a T5577/EM4100 the completer and
input_hint had nothing — no command suggestions, no hex/binary opcode hints. Now LF chips
get catalogs like the HF ones:

- T5577 catalog: READ(block) / WRITE(block, data) / WAKE(password) / DETECT(), with the
  downlink opcode exposed via build() for hex+binary completion, block-role hints (0=config,
  7=password, 1-6=data), and execution via a new run() path (LF isn't a raw-byte exchange —
  it drives lf.t55 / the demod). READ(0)/DETECT use the reliable rotation-fixed config read;
  data-block reads are best-effort and labelled as such. capture.read_t55xx_block added.
- LF read-only credentials (native EM4100/HID/AWID/FDX-B) get a minimal catalog (INFO -> re-read).
- catalog_for dispatches protocol "lf": "T5577" in the label -> T5577, else read-only.
- TagCommand gains an optional run(device, *args); completer/_opcode tolerate build=None.

Hardware-verified: identify -> catalog T5577, help lists the commands, DETECT()/READ(0) return
config 00148040 (EM4100). Tests: LF resolver, T5577 opcodes, T5577 block-role hints.
