Waleed 011f26d9f3 refactor: remove dead code, orphan modules, and two unused dependencies (#7063)
* refactor: remove dead code, orphan modules, and two unused dependencies

Every symbol below was classified per reference hit as: own declaration /
barrel re-export line / vi.mock stub / real production caller. Only symbols
with zero real callers are removed.

Orphan modules (nothing imports them):
- scheduled-tasks/components/schedule-calendar/ — 11 files. Zero references
  repo-wide, not even a barrel line.
- terminal/components/filter-popover/ — re-exported through a barrel,
  consumed by nothing.
- 6 iso-marks primitives (IsoCubeGrid, IsoCubeRow, IsoFourBox, IsoGridPlane,
  IsoStackedPlanes, IsoStar). mothership.tsx imports only the four
  Iso*Illustrations, which do not use these.
- 4 copilot user-input hooks (useMentionKeyboard, useTextareaAutoResize,
  useMentionInsertHandlers, useCaretViewport) — barrel line only. Their six
  siblings in that directory are live and stay.
- lib/workflows/application/duplicate-workflow.ts — an orphaned authorized use
  case. Live duplication goes through lib/workflows/persistence/duplicate.ts,
  which exports a same-named duplicateWorkflow; the 23 apparent references are
  all to that one. Nothing imports the application path.

Dead exports:
- lib/compare/data/feature-catalog.ts (SIM_FEATURES, 939 lines) plus the
  SimFeature type, FeatureCategory union, and featuresByCategory/featuresByTag
  helpers that only it used — one unshipped feature-comparison catalog.
- createExecutionCallbacks (execution-events.ts) — declaration only, zero
  other hits repo-wide.

Stale vi.mock targets — mocks whose module no longer exists, so they are
silent no-ops that make a test look protected when it is not:
- @/background/logs-webhook-delivery and @/app/api/webhooks/utils in the
  webhook trigger route test (its generateRequestHashMock and
  validateSlackSignatureMock hoisted vars went with it)
- @/lib/workflows/subblocks/options in blocks/blocks/logs.test.ts
- @/lib/uploads/setup in the S3 client test
- @/lib/uploads/setup.server in the files delete and parse route tests —
  parse/route.test.ts mocks the real @/lib/uploads/core/setup.server on the
  very next line

Dependencies: three and @types/three. Zero imports anywhere, and absent from
every config, script, workflow, Dockerfile and chart. Both arrived with the
speech-to-speech voice mode, which has since been removed.

Deliberately kept: build-chat-animation/ reads as an orphan but
build-callout.tsx documents it as parked unwired for reuse.

* chore: update lockfile for the three/@types/three removal

CI runs bun install --frozen-lockfile, so dropping the two dependencies from
apps/sim/package.json without regenerating bun.lock fails the install step.

The diff is the two entries plus three's transitives (@dimforge/rapier3d-compat,
@tweenjs/tween.js, @types/stats.js, @types/webxr, @webgpu/types, meshoptimizer).

One change deserves a note: top-level fflate moves 0.8.3 -> 0.4.8. It was
hoisted to 0.8.3 only because @types/three required ~0.8.2; with that gone the
remaining top-level consumer is posthog-js, which asks for ^0.4.8. Every other
consumer keeps its own pinned nested entry (@shuding/opentype.js 0.7.4,
@smithy/middleware-compression 0.8.1), and no source file imports fflate
directly, so no resolution changes for anything that was already installed.
