v4.43.0

Changes since v4.42.0 (2026-09-21).

Added

• providers(zai): new glm-5.3-flashx model — the ~200 tokens/s FlashX
  variant of GLM-5.3, with the same limits as glm-5.3-flash
  (1M context / 128K output); pricing (USD per 1M tokens)
  $0.37/$0.075 (cache hit)/$1.25.

Changed

• tests: rewrite the usage-line rendering tests to comply with
  dev-docs/testing.md Rule 6 (numbers over words). test_turn_report.py
  and test_usage_line_style.py now parse the === ... === summary line
  into labeled parts and assert values composed from the source-of-truth
  format_tokens() / format_elapsed() instead of pinning
  "In: 60/65.5k"-style strings; test_input_tokens_info.py drops its
  local replica of the parts-building logic and renders through the real
  janito.ui.usage._display_usage (close #152).
• providers(xiaomi): replace MiMo-V2.5 with the MiMo-V2.6 series
  (mimo-v2.6-pro, mimo-v2.6-flash, mimo-v2.6-pro-ultraspeed);
  the default model is now mimo-v2.6-flash. Limits are unchanged
  (1M context / 128K output); per-model pricing (USD per 1M tokens):
  Flash $0.14/$0.0028 (cache hit)/$0.28, Pro $0.435/$0.0036/$0.87,
  UltraSpeed $4.35/$0.036/$8.7 (close #150).
