Tech/migrate state util into features (#4504)

* refactor(visualization): move gameObjectsParser util into navBar feature

Sole consumer is navBar/services/readFiles.ts; relocate the whole
gameObjectsParser module (importer, validator, schema, mocks, specs)
into features/navBar/util/. Verified by dependency-cruiser (0 errors)
and jest.

* refactor(visualization): remove dead truncateText pipe

TruncateTextPipe had no template usage and no class references outside
its own spec. Removing the orphan. dependency-cruiser clean.

* docs: record verified outcome of state/util-into-features analysis

Re-verified every fan-out move candidate against the real import graph
with dependency-cruiser + jest. Most util predictions were wrong (grep
blind spot for intra-util relative imports / state-core consumers /
app.config effect registration). Only gameObjectsParser move + dead
truncateText pipe deletion held up.

* refactor(visualization): drop dead buildingArrayToMap to break treeMapHelper cycle

buildingArrayToMap had no production callers (only its own test) and was
the sole reason util/algorithm/treeMapHelper imported CodeMapBuilding from
the codeMap feature. Removing it eliminates the util->feature inversion and
30 of the 126 no-circular warnings (126 -> 96). CodeMapBuilding stays in
the codeMap feature where it belongs.

* refactor(visualization): move CodeMapBuilding fixtures out of dataMocks into codeMap

The 5 CodeMapBuilding test fixtures (CODE_MAP_BUILDING*, CONSTANT_HIGHLIGHT)
lived in the shared util/dataMocks god-file but are consumed only by codeMap
specs, forcing util/ to import up into the codeMap feature. Move them to a
codeMap-owned features/codeMap/rendering/codeMapBuilding.mocks.ts and repoint
the 3 codeMap specs. Removes the last util->codeMap inversion; CodeMapBuilding
stays in the feature. dependency-cruiser 0 errors, 143 tests pass.

* refactor(visualization): extract dataMocks from util into its own mocks/ root folder

dataMocks is a ~2500-line cross-layer test-fixture file that was sitting in
util/ and obscuring real util problems. Move it to app/codeCharta/mocks/ (a
sibling of util/), repoint all 57 importers, and fix its one same-dir import
(./codeMapHelper -> ../util/codeMapHelper). Pure relocation: dependency-cruiser
0 errors, tests green across every import depth.

* build(visualization): exclude test fixtures from dependency-cruiser analysis

dataMocks (now in mocks/) and *.mocks.ts files are test fixtures, not
production architecture, yet dataMocks alone added ~67 edges as a hub node
that obscured real structure in the graph. Exclude mocks/ and *.mocks.ts so
the dependency graph and boundary rules reflect production code only
(fixtures are imported solely by tests). 4622 -> 4555 dependencies cruised.

* refactor(visualization): remove dead mockHelper

mockHelper.ts had zero references anywhere (production or test). Orphan, like
the truncateText pipe — removed.

* refactor(visualization): move file-ingestion parser into loadFile feature

fileParser + fileValidator are consumed only by loadFile in production, so
relocate them to features/loadFile/util/. The one cross-feature consumer (the
globalSettings spec using getNameDataPair) now imports it via loadFile's public
facade, which is the depcruise-legal way to cross features. generatedSchema.json
stays in util/ (generated artifact) and is imported feature->util. mockHelper
already removed. dependency-cruiser 0 errors, 74 tests pass.

* refactor(visualization): break codeCharta.model import cycles

codeCharta.model (the leaf domain types) was reaching up into two higher
layers, forming type-only cycles:
- NameDataPair.content needed ExportCCFile -> codeCharta.model <-> codeCharta.api.model
- CcState.files needed FileState -> codeCharta.model <-> model/files/files

Fix by making the leaf stop importing upward:
- Move NameDataPair into codeCharta.api.model (next to ExportCCFile); repoint
  its 8 type importers.
- Move FileState/FileSelectionState into codeCharta.model; model/files/files
  re-exports them (natural files->model direction), so its 47 importers are
  untouched.

Both edges removed: dependency-cruiser warnings 96 -> 94, 0 errors, tests green.

* fix(visualization): correct fileValidator path in navBar e2e

The fileValidator move left a 4-level relative path pointing at codeCharta/
instead of features/loadFile/. e2e files aren't type-checked by jest and
depcruise ignores unresolvable modules, so tsc surfaced it.

* refactor(visualization): split codeCharta.model into domain + state behind a barrel

Step 1 of incrementally breaking up the 363-line model god-file. Definitions
now live in model/domain.model.ts (leaf .cc.json domain types) and
model/state.model.ts (the ngrx state tree, which imports the domain one-way).
codeCharta.model.ts becomes a pure barrel re-exporting both, so all 416
existing importers keep working unchanged. Consumers can migrate to the
specific files over time, then the barrel can be dropped.

Verified: dependency-cruiser 0 errors / 94 warnings / no new cycles, tsc 0
errors across all importers, model tests green.

* refactor(visualization): consolidate cc.json read path into loadFile + pin the wire DTO

loadFile now owns cc.json ingestion: moved urlExtractor in, and extracted the
wire-parsing functions (getCCFile, getCCFileAndDecorateFileChecksum) out of the
mixed util/fileHelper into loadFile/util/ccFileHelper. The cross-feature callers
reach them through loadFile's facade (navBar upload, globalSettings url-reset).
util/fileHelper keeps only getSelectedFilesSize (a FileState helper, no wire
format). fileDownloader (export side) stays shared.

Adds a dependency-cruiser rule 'wire-dto-only-in-serialization-boundary' that
confines codeCharta.api.model to the loadFile feature, the navBar gameObjects
importer, and util/fileDownloader — so rendering/state/UI can't couple to the
wire format and the upcoming cc.json 2.0 change stays contained to the converter.

tsc 0 errors, dependency-cruiser 0 errors / 94 warnings, tests green.
