- SrasFile: _parse_v6 now retains per-angle x_delta and the verbatim
preamble/background byte spans, and gains public data_offset,
y_pos_per_angle, and iter_angle_blocks() (which now owns the ragged
block-offset walk used three separate places before).
- sras_edit_scans: the 70-line re-parse of the v6 header sections
(_read_v6_sections/_reread_span/_v6_angle_offsets) collapses into a
_write_v6 that consumes SrasFile directly — verified byte-identical
round-trip on v6 int8/int16 and legacy files. Eight print-and-exit
pairs become _die().
- tools/make_test_sras imports the struct layouts from sras_format and
the rotation matrix from sras_compute instead of re-declaring them
(byte assembly stays independent of the reader).
- sras_compute: block_mean_2d, pixel_pitch_mm, nominal_delta_deg made
public (they were GUI-facing); registration_workers() and
default_max_workers() wrap the remaining private reach-throughs from
sras_workers.
