Rad f758028de0 Add release notes for v0.92 and refactor mixed filament gradient handling

- Introduced a new `RELEASE_NOTES_v0.92.md` file detailing highlights such as gradual gradient behavior, mixed filament indexing fixes, and editable automatic mixed filaments.
- Refactored `compute_gradient_ratios` to remove the cycle layers parameter, implementing a new gradual integer cadence for gradient transitions.
- Updated `MixedFilament` structure to include an `origin_auto` flag for better management of auto-generated entries.
- Adjusted related parsing, serialization, and UI handling to reflect these changes, ensuring improved user experience and color fidelity in mixed filament rendering.

Raw Blame History

Snapmaker Orca Full Spectrum v0.92 (Pre-release)

Mixed-filament stability and workflow release. Based on Snapmaker Orca v2.2.4.

Highlights

Gradient Behavior Is Now Gradual

Removed the Mixed filament layer cycle setting.
Reworked non-height-weighted gradient math to use gradual integer cadence by ratio (minority side anchors to 1 layer, majority side scales progressively).
This prevents abrupt jumps in layer cadence and makes transitions more predictable.

Mixed Filament Indexing And Mapping Fixes

Fixed mixed-filament row labeling so IDs stay compact after deletions in the Mixed Filaments panel.
Fixed regeneration order so auto-generated/precomputed mixes are appended at the end of existing mixed rows instead of being inserted at the front.
Fixed paint/index remapping when adding physical or virtual filaments so existing painted mixed regions keep their intended virtual filament mapping.
Fixed edge case where the first mixed filament could be temporarily replaced by a newly added physical filament.

Automatic Mixed Filaments Are Editable

Automatic mixed rows can now be expanded and edited through the gradient controls.
Edited auto-origin rows are treated as user-managed entries.
Deleting an edited auto-origin row now keeps that auto pair tombstoned (it will not be regenerated immediately and overwrite user intent).

Gradient Preview Color Fidelity

Updated gradient preview blending to use the FilamentMixer library path for color reproduction.
Preview swatches now better match expected mixed output.

Selective Expansion/Contraction Fix

Updated selective mixed-zone contraction so positive values trim only the outside-facing (visible) boundary band.
Internal/shared boundaries are no longer symmetrically contracted.
Outward expansion behavior remains unchanged.

Also Included (v0.91 Carry-Forward Fixes)

Windows startup/log path handling for non-ASCII usernames (UTF-8-safe path resolution).
Mixed-filament swatch desync/gray-regression fixes in preview rendering.

Internal/Config Changes

Removed mixed_filament_cycle_layers from config/UI wiring.
Extended mixed filament serialized metadata with auto-origin tracking to preserve delete/regenerate intent across reloads.
Added diagnostic logging around mixed-filament remap and selective-indentation application paths.

Important Notes

Experimental build with limited testing.
Some projects may show different gradient cadence behavior due to the removal of explicit layer-cycle control.
Use at your own risk.
