fix: replace remaining glob('*.md') with rglob('*.md') in all adaptors

Follow-up to #349 — the same bug existed in 4 more adaptor files:
- base.py (2 locations) — affects all adaptors via inheritance
- openai_compatible.py (2 locations) — affects minimax, deepseek,
  kimi, qwen, openrouter, together, fireworks
- markdown.py (1 location)
- streaming_adaptor.py (1 location)

No glob("*.md") remains in any adaptor.
