The MiniMax-M3 long-context policy in generated-policies.ts only
covered the anthropic-messages providers `minimax` and `minimax-cn`.
The MiniMax Coding/Token Plan (international and China) endpoints
serve the same model through `minimax-code` and `minimax-code-cn`
on openai-completions, and shipped with the upstream 512K pricing
boundary baked into models.json. Switching to MiniMax-M3 under the
Coding Plan therefore still showed a 512K context window in the
status bar.
Broadens the policy carve-out to all four providers, re-bakes both
affected entries in the bundled models.json, and extends the
generated-policies / bundled-catalog tests to assert 1M for the two
newly covered providers.
