// ingest — the "ingest through the bank" shell (EXTENSION side). REAPER-facing
// (PCM_Source metadata reads, Media-Explorer query, ext-state assignment write,
// action registration), so DAW-verified, not unit-tested; the pure serialization it
// drives lives in assignment_request (CTest).
//
// Loading a sample into the sampler is ONE gesture: capture/import-into-bank AND
// auto-assign to the active sampler instance. The EXTENSION owns ingest (arrange
// access, Media-Explorer access, drop-target surface); the instrument stays a
// READ-ONLY bank consumer. Three surfaces: (1) arrange capture -> bank -> assign,
// (2) Media-Explorer import -> bank -> assign (single-file, pull-on-action), (3)
// drop-onto-panel -> bank -> assign (multi-file: import all, assign the first).
//
// LOAD-BEARING: ingest NEVER inserts a timeline item — capture writes a file + index
// entry, import copies a file + adds an index entry, assignment is a bank-index +
// instance-selection act, not a placement. Any InsertMedia call here is a bug.
//
// Import is a FILE COPY into the project-relative bank folder + an index add
// (relative-paths-only, hash-dedup). If the active bank already holds the content
// (by hash), the import collapses onto the existing sample instead of duplicating.
