v1.5.0: invalid-INS one-byte re-frame + explicit discard logging
Residual CONCAT mis-frames (4gmodem/A55_sim2/S21p_sim2) traced to a silent 5-byte drop at an invalid-INS T=0 header (0x0f 00 a4 08 04). Drop only the stray leading byte and re-frame the remaining four via _replay so the real command (00 a4 08 04 02 2f 00 -> 61 1c) is recovered. - _note_discard()/_consume_first(): every consumed-but-unemitted byte is now logged; idle 0x00/0xFF discards are rate-limited, real data always gets an ANN_WARN annotation. - All read-until-SW loops log skipped non-SW bytes. - All traces: CONCAT 0; BAD_FCS/GARBAGE 0; test_8/test_7 RESULT OK; 47/47 unit tests; baseline byte-identical. History rewritten to a single root commit so no example trace is stored in the repo (fixtures are local-only, gitignored). README keeps only generic <trace>.sr placeholders; AGENTS.md retains the fixture names.
