docs: sync README files with latest repo state

[yyiilluu]

Summary

• Refreshes OSS server code-map READMEs for newly added scheduler infrastructure and missing-vector backfill navigation.
• Follows the parent repository's how_to_write_readme.md guidance for concise, path-focused code maps.

Repositories/submodules reviewed

• Parent: ReflexioAI/reflexio-enterprise
• Submodules: open_source/reflexio, open_source/claude-smart

README files updated

• reflexio/server/README.md
• reflexio/server/services/README.md

Validation

• git diff --check
• python /root/.hermes/skills/github/scheduled-code-map-readme-maintenance/scripts/readme_link_check.py /root/reflexio-enterprise/open_source/reflexio reflexio/server/README.md reflexio/server/services/README.md

Notes/Risks

• Documentation-only change.
• open_source/reflexio/README.md was intentionally not modified because it is the user-facing public README excluded from code-map restructuring.

Summary by CodeRabbit

• Documentation
  • Updated server documentation to describe scheduler infrastructure and shared service components.
  • Clarified search preparation capabilities, including vector backfill repair.
  • Documented the optional missing-vector repair sweep and its configuration limits.

📝 Walkthrough

Walkthrough

The server and services READMEs now document scheduler infrastructure, expanded search preparation responsibilities, and the opt-in per-organization vector backfill sweep with its configuration flags.

Changes

Scheduler and vector backfill documentation

Layer / File(s)	Summary
Infrastructure index reflexio/server/README.md, reflexio/server/services/README.md	Documents ThreadedScheduler, the bounded callback executor, and the organization fan-out helper.
Vector backfill index reflexio/server/README.md, reflexio/server/services/README.md	Adds vector backfill repair to search preparation and documents the opt-in vector_backfill_sweep.py lineage sweep with enablement and cap settings.
