The 2790-line module becomes sras_viewer/: common.py (constants +
layout helpers), canvases.py (RoiQuad, ImageCanvas, WaveformCanvas,
ManualAlignOverlayCanvas), dialogs.py (FftOptionsDialog,
ManualAlignmentDialog), main_window.py (SrasViewerWindow + main), with
__init__ re-exporting the public names and __main__ keeping
`python -m sras_viewer` working. pyproject gains a `sras-viewer`
console script.
Code moved verbatim; only import headers are new (pyflakes-clean).
tests/test_gui.py patch targets follow the classes to their new
modules.

- 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.

- pyproject.toml replaces sras_viewer_requirements.txt (same pins) and
adds a dev extra with pytest.
- tools/test_refactor.py, test_alignment.py, test_gui.py become
tests/test_compute.py, tests/test_alignment.py, tests/test_gui.py with
assertions preserved verbatim. test_gui.py stays one ordered
integration sequence over a shared module-scoped window.
- check_equivalence.py: drop the dead pre-refactor monolith shim (and the
_compute_angle_alignment alias it consumed), extend the pad sweep to
(1, 2, 4, 8, 40), add legacy-v4 and big-endian int16 legs (new bps=2
option in make_test_sras) so the padded FFT path and the >i2 memmap
path are in the baseline before the FFT rewrite.
