## Problem

The review of werkregie PR#26 got no model review:
`APIError: Empty content in model response (finish_reason: length)`, twice, in 506 s.
MiniMax M3 spent the whole `max_output_tokens = 32000` on reasoning and wrote no answer.
PR-Agent raises an error for empty content, so werkrevisor's own check `truncated` never sees the answer,
and the handler repeats the same request once.

The result comments of 211 successful MiniMax reviews in the werk repositories show the output tokens per call,
reasoning included:

| Statistic | Output tokens |
|---|---|
| Median | 13825 |
| 90th percentile | 25543 |
| 95th percentile | 30997 |
| Maximum | 47050 |

8 of the 211 exceeded 32000; all of them ran in werkrevisor, whose limit is 48000.
werkator, werkcrappit and werkregie have 32000, so about 1 review in 25 ends without a model answer there.
The output does not follow the input: a review of 12168 input tokens wrote 43621.

## Non-Goals

- No change of `reasoning_effort`: `low` and `none` missed a finding on 1 of 4 heads each.
- No bound of the reasoning with `reasoning_max_tokens`; whether MiniMax keeps it is not measured.
- No change of the retry after an empty answer.

## Solution

- `max_output_tokens = 64000` for MiniMax M3 in `config/werkator.toml`, `config/werkcrappit.toml`,
  `config/werkregie.toml` and `config/werkrevisor.toml`.
- `max_usd_per_review = 0.25` in all four, so that the input limit stays at `max_context_tokens = 150000`:
  2 calls of 150000 input and 64000 output tokens cost at most about 0.24 USD.
  A review costs more only when the model really writes more.
- The README's table of model limits names 64000 for MiniMax M3.
- Werkbaum: `#model.output`, and the idea `#model.empty` for the retry after an empty answer.
- Version 0.32.10.
