Incorrect node map for ComfyUI-H3-Continuum: 43 nodes listed, includes VAEDecodeAudio and test fixtures

## Summary

The `extension-node-map.json` entry for:

`https://github.com/ukr8b3g-cmyk/ComfyUI-H3-Continuum`

is stale/incorrect. ComfyUI-Manager currently reports **43 nodes** and **1 conflict**, with `VAEDecodeAudio` shown as conflicting with ComfyUI Core.

The current H3 Continuum V3.8 public surface exports only **7 nodes**. `VAEDecodeAudio` is a ComfyUI Core node used by the workflow and is not exported by H3 Continuum.

## Current incorrect mapping

The Manager DB currently includes many historical/internal/test-only IDs, including examples such as:

- `H3ContinuumAdvanced`
- `H3ContinuumSamplerV2` ... `H3ContinuumSamplerV37`
- `H3CoreContinuumGpuDiagnostic`
- `P24ClearCacheOutput`
- `P24DecodedFixture`
- `P25StoredLongTerminalFixture`
- `P25SyntheticDecodedStressFixture`
- `VAEDecodeAudio`

This causes the Manager UI to show `43 nodes` and `1 conflict` (`VAEDecodeAudio`).

## Expected mapping

Please replace the H3 Continuum node list with the current V3.8 public surface only:

```json
[
"H3ContinuumSamplerV38",
"H3ContinuumReferenceAudios",
"H3ContinuumAssembleSeamV35",
"H3EasyLoadImage",
"H3EasyLoadAudio",
"H3ContinuumLoadVideo",
"H3ContinuumSecondPassV35"
]
```

These are the IDs retained by the repository's final `_PUBLIC_NODE_DISPLAY_NAMES` filtering in `nodes.py`.

## Reproduction

1. Use current ComfyUI-Manager `main` (`f82970b7cb63ad44928308f980a1d38fda103cbb`).
2. Open Manager and inspect **H3 Continuum**.
3. It reports `43 nodes` / `1 conflict`.
4. Expanding the card shows historical/internal/test IDs plus `VAEDecodeAudio`.
5. Removing the cached `extension-node-map` does not fix it because the stale mapping is fetched/recreated from the Manager DB/channel.

## Notes

- H3 Continuum itself should not be changed for this issue; its current public mapping is already limited to the 7 IDs above.
- The stale mapping appears in the Manager `extension-node-map.json` / `node_db/new/extension-node-map.json` data for this repository.
- Removing `VAEDecodeAudio` from the H3 Continuum mapping also removes the false conflict with ComfyUI Core.

Inspect the H3 Continuum entry in extension-node-map.json or node_db/new/extension-node-map.json, then compare it with the seven IDs retained by nodes.py's final _PUBLIC_NODE_DISPLAY_NAMES filtering. Replace the stale list with those seven public nodes and verify that the Manager shows 7 nodes with no VAEDecodeAudio conflict.
