feat: add deepseek/deepseek-v4-flash to OpenRouter model catalog

[Sullipaupau]

deepseek/deepseek-v4-flash is live on OpenRouter and supports tool calling, but it was missing from both the curated catalog manifest (website/static/api/model-catalog.json) and the hardcoded fallback (hermes_cli/models.py OPENROUTER_MODELS).

This means the /model picker never shows it as an option — users who want to set it as their default model have to manually hermes config set model.default.

Changes

• Added deepseek/deepseek-v4-flash to website/static/api/model-catalog.json (OpenRouter provider block)
• Added deepseek/deepseek-v4-flash to hermes_cli/models.py OPENROUTER_MODELS fallback list (right after deepseek-v4-pro)

Verification

# Flash is on OpenRouter live API with tool support
curl https://openrouter.ai/api/v1/models | jq '.data[] | select(.id | startswith("deepseek/deepseek-v4")) | {id, tools: (.supported_parameters | contains(["tools"]))}'
# deepseek-v4-flash: tools=true
# deepseek-v4-flash:free: tools=true
# deepseek-v4-pro: tools=true

[alt-glitch]

Duplicate of #26130 which re-adds deepseek/deepseek-v4-flash to the model catalog (Nous Portal + OpenRouter). Flash was added in #14934, removed in #16197, and v4-pro re-added in #20495 but flash was not.

Thanks for the focused catalog update. This is an automated hermes-sweeper review; the requested behavior is already on current main.

• hermes_cli/models.py:65 includes deepseek/deepseek-v4-flash in OPENROUTER_MODELS.
• website/static/api/model-catalog.json:92 includes the same model in the OpenRouter manifest.
• hermes_cli/models.py:1392-1402 confirms these curated sources feed the OpenRouter picker path.
• Commit 50db2d9c12f2734b4ba8bbeb3c92a6e14e786a02 (feat(models): add deepseek-v4-flash, trim variants, group curated lists by maker (#35659)) implemented this exact catalog addition.
