fix(core): validate transforms without emit

[samchon]

Intent

Make ttsc --noEmit, configured noEmit, and the native check command surface the same typia/core/SDK contributor diagnostics as an emitting nestia build, while ensuring failed builds cannot leave runnable untransformed output.

Closes #1624.

Scope

• reload a private emit-enabled program after the original no-emit program passes TypeScript diagnostics, then run the complete composed transform pipeline with every output discarded;
• route check through the same no-emit build path so the two commands cannot diverge;
• buffer declarations, JavaScript, maps, and build metadata until emit and transform diagnostics are clean;
• pin LLM-only tuple return diagnostics for TypedRoute across check, explicit --noEmit, configured noEmit, and normal failed emit paths;
• assert the real ttsc CLI reports the detailed nestia.core.TypedRoute diagnostic and publishes no failed output;
• update typia, @typia/interface, and @typia/utils to 14.0.2 so nestia consumes the upstream runtime guidance release.

@nestia/sdk needs no separate execution change: its compiler already propagates the core host's nonzero status and stderr. No package version fields are changed; release versioning remains maintainer-owned.

Local verification

• go test ./... -run 'TestBuild(NoEmitReportsLlmRouteDiagnostic|TransformDiagnosticPublishesNoArtifacts|NoEmitPreservesAnalysisOnlyOptions)$' -count=1 -v
• pnpm --filter ./tests/test-transform-options start
• pnpm format
• git diff --cached --check

The full pnpm --filter @nestia/core test:go run was intentionally stopped before completion at maintainer direction; the complete repository matrix is deferred to GitHub Actions.

Self-Review round 1 — finding fixed

Reviewed immutable commit a4339e8c3ea36ca53854c6bfa1eff311ddb3a750 across the complete pull-request diff and the compiler-driver, SDK consumer, platform, recovery, packaging, documentation, and CI consequence surfaces.

One sound concurrency defect survived verification: TypeScript-Go's declaration emitter queues source files in parallel, while the new deferred-output callback appended to the shared emitted and pending slices without synchronization. A declaration build could therefore race or lose a buffered artifact. Commit cdd8d09af8aabee9320e632da2bcd44336658b31 serializes those callback writes.

Because the review produced a change, this round is not the final clean gate. A fresh whole-surface round is running against cdd8d09af8aabee9320e632da2bcd44336658b31 while its replacement CI matrix executes.

Self-Review round 2 — clean

Reviewed immutable commit cdd8d09af8aabee9320e632da2bcd44336658b31 from scratch across the complete base-to-head diff and its compiler-driver, typia/core/SDK composition, declaration/JavaScript/map/build-info/manifest publication, no-emit and failure recovery, concurrency, Windows/POSIX, Express/Fastify, generated SDK/Swagger/e2e, packaging, documentation, migration, and CI consequences.

No further sound improvement survived verification. The round confirmed:

• check, explicit --noEmit, and configured noEmit run the complete composed transform and publish no artifacts;
• LLM-incompatible TypedRoute return types report the exact nestia.core.TypedRoute compile diagnostic instead of deferring to runtime NoTransformConfigurationError;
• failed emitting builds publish no declarations, JavaScript, maps, build info, or manifest;
• the SDK contributor shares the core host and SDK callers preserve the host's nonzero status and stderr, so no separate SDK execution patch is required;
• buffered declaration callbacks are serialized before the final clean-only flush;
• typia, @typia/interface, and @typia/utils resolve consistently to 14.0.2.

GitHub Actions completed all 21 pull-request checks successfully, including go, sdk, transform-options, e2e, Ubuntu build, both format jobs, and both Ubuntu/Windows benchmark-system jobs. No verification remains skipped beyond the already disclosed interrupted local full-Go run, whose complete matrix was delegated to and passed in CI.
