Merge branch 'main' into feature/filament_id

Brings in 560 commits (merge base 2026-07-04 .. origin/main af9fd10d7a).
19 conflicts resolved; the other 138 touched files auto-merged.

Conflict resolutions
- Snapmaker/Polymaker (7): main normalised JSON key order in #15039 while this
  branch inserted filament_id/filament_vendor. Took main's key order and kept
  this branch's values, inserting a single filament_id key rather than letting
  git's line merge leave duplicate "from"/"instantiation" keys.
- re3D rPETG @0.8/@1.75 nozzle (2): main renamed these from "re3D Greengate
  rPETG @*" and re-vendored GreenGate3D -> re3D (#15169). Git's rename-aware
  merge produced a file with two filament_vendor keys; took main's version
  wholesale instead. The id is reconciled by the tooling, not by hand.
- re3D rPP (1): kept main's inherits change (fdm_filament_pet -> fdm_filament_pp,
  local filament_type override dropped) and its widened compatible_printers.
  The flattened type is still PP, so the product triple and id OFfHGM1D are
  unchanged.
- re3D Greengate rPETG.json, Afinia {ABS+,ABS,PLA,TPU,Value ABS,Value PLA}.json
  (7 modify/delete): accepted main's deletions. The Afinia ids are not orphaned
  - the surviving @HS presets resolve the same triple and already carry the
  same ids, so nothing is retired.
- .github/workflows/check_profiles.yml: kept both main's new "validate slice"
  step and this branch's tree-wide filament-subtype check.
- tests/libslic3r/CMakeLists.txt: kept both test_filament_id_succession.cpp and
  main's test_preset_diff.cpp.

Verified
- No conflict markers; all 12795 profile JSONs parse with no duplicate keys.
- All branch artifacts (tooling, snapshot, ledger, doc, tests) intact and
  unmodified by the merge.
- The succession-ledger C++ call sites survived main's refactors; audited
  Preset.{cpp,hpp}, PresetBundle.cpp, DeviceManager.cpp, PresetComboBoxes.cpp,
  CaliHistoryDialog.cpp, MoonrakerPrinterAgent.cpp against base/ours/theirs.
- scripts/tests: 115/116 pass.

Known follow-up: assign_filament_ids.py --check reports 243 errors, all from
filament data main added in the last month (BBL/addnorth, Qidi X5/Plus 5,
Snapmaker U1, re3D). The single failing unit test is the live-tree conformance
test asserting that count is zero. Reconciliation lands separately.
