fix(s08): support recursive glob and conditional micro compact

[0xJieREN]

Summary

• enable recursive ** matching in the s08 glob tool
• run micro_compact only when the context exceeds CONTEXT_CHAR_LIMIT
• re-check the context size after micro compaction before invoking full history compaction
• add regression coverage and synchronize the s08 trilingual docs, diagrams, and generated web content

Verification

• uv run --with pytest --with anthropic --with python-dotenv --with pyyaml python -m pytest tests -q — 226 passed, 92 subtests passed
• npm run build — production build completed successfully (118 static pages)
• git diff --check

Closes #531
