Check Comfy model download status

[andreip135]

Templates: https://github.com/oceanprotocol/ocean-node-templates/pull/27

Summary by CodeRabbit

• New Features
  • Startup readiness is reported for supported vLLM, llama.cpp, and ComfyUI services when their required ports are exposed.
  • Model-download progress can be reported from a download manifest, including for services without a readiness probe. Progress reporting for these services is time-limited.
  • Services still waiting for readiness after 15 minutes receive a warning that may include download progress.
• Documentation
  • Added guidance on readiness states and image-pull and model-download progress reporting.

📝 Walkthrough

The change adds manifest-based model-download progress, adjusts engine recognition to require published probe ports, and adds ComfyUI readiness support. It also adds delayed readiness warnings, permits progress updates without readiness data, and bounds container disk-usage collection.

Changes: Service readiness and model-download progress

Layer / File(s)	Summary
Manifest format and download accounting src/@types/C2D/ServiceOnDemand.ts, src/components/c2d/downloadManifest.ts, src/components/c2d/modelDownload.ts, src/test/unit/service/downloadManifest.test.ts	The download record adds optional filesTotal. Manifest entries are parsed and measured for file and directory progress. Completion uses filesTotal when available. Tests cover parsing, sampling, and completion.
Engine selection and readiness warnings src/components/c2d/serviceEngines.ts, src/components/c2d/serviceReadiness.ts, src/components/c2d/compute_engine_docker.ts, src/test/unit/service/serviceReadiness.test.ts, src/test/unit/service/readinessWarning.test.ts	Engine resolution requires a published probe port and adds a ComfyUI profile. Waiting services receive one warning per container after 15 minutes. Tests cover engine resolution and warning timing.
Runtime sampling and progress persistence src/components/c2d/compute_engine_docker.ts, src/components/database/C2DDatabase.ts, src/components/database/sqliteCompute.ts, src/test/unit/service/unprobedServiceDownload.test.ts, docs/services.md	Runtime probing samples manifests before engine-cache progress. Unrecognized engines can report download progress without readiness. Database updates preserve stored readiness when none is supplied. Disk-usage collection uses a 15-second timeout. Tests and documentation cover these behaviors.

Merge Risk: 🔵 Low · up to 7c484

Download progress may omit some models or report completion early for long lists, while recognized services may repeat disk measurements. These bounded concerns warrant owner awareness before merging.

- Around line 63-64: Update the entry limit handling in the model-list sampling
flow so it detects when `.models.tsv` contains more than `MAX_ENTRIES` valid
destinations and does not publish a definitive `filesTotal` for the truncated
list. Preserve the existing cap on retained entries.
- Around line 55-56: Update isHubFileUrl to accept the supported model filename
formats instead of requiring the path to end in .safetensors, while preserving
the existing host and path-segment checks so all bundle downloads are included
in sampler totals.
