Extract shared MiniMax provider logic into minimax-shared.js factory
module used by both minimax-coding-plan and minimax-cn-coding-plan
as thin wrappers.
Endpoint fallback:
- Try /v1/token_plan/remains (M3/Token Plan) first
- Fall back to legacy /v1/api/openplatform/coding_plan/remains
- fetchEndpoint wrapped in try/catch so network/parse errors
return null instead of throwing, ensuring fallback always runs
Model selection (pickChatModel):
- Prefer MiniMax-M* entries with non-zero total_count (Token Plan M3)
- Fall back to general/chat/text model names (legacy Coding Plan)
- Fall back to any entry with current_interval_remaining_percent
- Ultimate fallback to model_remains[0]
Usage calculation:
- token_plan endpoint: usage_count = remaining, so used = total - remaining
- coding_plan endpoint: usage_count = consumed (legacy behavior)
- Prefer current_interval_remaining_percent when count fields are zero
(legacy Coding Plan accounts with percentage-based quotas)
- remains_time used as fallback for window duration (in milliseconds,
confirmed via live API: 9664502ms = 2.68h in 5h window)
Window status:
- Respect current_weekly_status field: status 3 means the window is
not applicable for the current plan tier (e.g. legacy plans without
weekly limits). These windows are omitted from the result.
- Default to active when status field is absent (backward compatible).
Fixes#759 (percentage showing empty/null for legacy Coding Plan
accounts and incorrect percentages for M3/Token Plan accounts).
