CCSDS TM Transfer Frames (CCSDS 132.0-B-3)
feat(wire.c): extract verified C libraries for all CCSDS protocols via EverParse
Add wire.c library with generate_3d (pure OCaml, fast) and generate_c
(EverParse pipeline, slow) split so dune only re-runs EverParse when
.3d schemas change. Build rules, tests, and install stanzas are generated
into dune.inc to minimize per-package boilerplate.
Each package gets a self-contained C library (header + single .c file)
with ~2000 validation tests covering position tracking, truncation,
boundary conditions, and fuzz.
