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

Thanks for the focused fix. I pushed two follow-up commits to extend bounded recursive glob behavior across the relevant lessons and align s08/s15 compaction so it runs only under pressure while every shortened result remains recoverable; the full Python suite, web build, and real-model checks for **/*.py plus a persisted 60K tool result all pass.
