Augments @bergeouss's PR #1548 v2 with the structural fix the issue
actually requested. The original PR added 5 hardcoded entries to
_FALLBACK_MODELS which would rot fast as OpenRouter's free-tier roster
turns over monthly.
Adds proper live-fetch logic to the OpenRouter group population so the
free-tier list stays fresh without requiring a code release every time
a new free model lands.
api/config.py:2120 — replaces the static _FALLBACK_MODELS slice with:
1. Live curated catalog via hermes_cli.models.fetch_openrouter_models()
— applies the tool-support filter (Kilo-Org/kilocode#9068).
2. Free-tier live fetch — direct call to https://openrouter.ai/api/v1/models,
filtered to free-tier-only (pricing.prompt == 0 AND pricing.completion
== 0, OR :free suffix), bypasses the tool-support filter so newly-added
free variants appear even before OpenRouter annotates them with tools.
Capped at 30 entries to keep the picker usable.
3. Defense-in-depth fallback to _FALLBACK_MODELS (which retains
@bergeouss's hardcoded list for offline / test envs).
4. Deduplication via seen_ids — model in both surfaces appears once.
5 new tests + 1 fixed test in tests/test_minimax_provider.py (scoped the
provider='MiniMax' assertion to direct-MiniMax routes by filtering for
'minimax/' prefix and excluding ':free' since the OpenRouter free-tier
variant minimax/minimax-m2.5:free correctly carries provider='OpenRouter').
