DRAFT: port optimizer presets and linked workflow parameters (#250–#251)

[JayceeB1]

Scope

Second-layer experimental integration on top of staging PR #3. Sources: upstream #250 and upstream #251, originally contributed by @OmarB97.

lightningpixel#250 — Optimizer presets (adapted to current Python engine)

• 0.4.3 runs the optimizer through api/services/mesh_ops/processor.py and a shared registry; do not reintroduce the legacy processor.ts.
• Built-in workflow picker offers Full detail (pass-through, default), 12k, 30k, 60k and 120k targets.
• Only the workflow adapter treats 1,000,000 as keep original file; direct mesh-operation API stays unchanged.
• Normalize values from HTML selects (strings) and bound model parameters (numbers), rejecting malformed/out-of-bounds inputs without touching the input mesh.
• Remove the redundant Library confirmation/footer UI from Replace triangle input and remove redundant Library footer lightningpixel/modly#250.
• Add 4 Python regression methods.

lightningpixel#251 — Workflow params and Library/viewer synchronization

• Add paramBindings to the workflow schema and resolve values from the freshest live upstream node params at target execution time.
• Suppress a redundant Generate question for fully bound extension nodes; dangling/self-referential bindings cannot hide the control.
• Add conservative parameter-key protection and 7 Node unit tests.
• Synchronize active animation clip and clip list via appStore, with reset when switching assets.
• Add Library clip selection matching, active-asset identity and zoom-aware viewport panel placement; add Library-focused regressions.
• Keep the current 0.4.3 viewer export and point-light code.

Evidence / limitations

• 5 isolated Python checks of the updated optimizer adapter passed (including missing assets, invalid values, 1M no-op, numeric bindings, unchanged other-op dispatch).
• 7 isolated Node tests of the exact workflow parameter-binding helper passed on Node 22.
• All edits confined to this child branch, not main or source PR branches.
• Not yet run: full combined Python and Node suites, TypeScript checks, lint and Electron build.
• Native Windows desktop smoke: optimizer output, clip switching, responsive Library popover, and restart persistence.
• End-to-end multi-node bindings on an actual TRELLIS → optimizer workflow.

See the updated docs/experimental-library-integration-ledger.md.

Do not merge to main or ship an installer based solely on these isolated tests. This is a reviewable port, not a proven release.
