Slicing from Bambuddy meant taking a process preset as-is; any change meant a round trip through Bambu Studio. The slice dialog now carries OrcaSlicer's full process tree -- pages, groups, labels, tooltips, ranges and defaults extracted from the slicer's own sources. Enable/disable rules are evaluated from the slicer's own enable_if expressions via a recursive-descent interpreter (no eval, CSP), with enum comparisons validated against each option's declared values. Anything undecidable leaves the field editable rather than greyed. Overrides apply after the source's support config (#1881) and the designer's carried tweaks (#2622), so an explicit choice always wins; an untouched panel sends the same request as before. Adds slice_engine as a separate setting from preferred_slicer -- where slicing runs is a different axis from which binary the sidecar drives. Only the sidecar engine is registered, so no picker renders yet.
