Stack-1 c215f4f404 docs: fix GitHub rendering of internals and PDF
- communication.md: replace the Mermaid state diagram with a plain-text
  diagram (Mermaid showed 'Error rendering embedded code' on GitHub)
- regenerate psblas-3.9.pdf as PDF 1.5 (matching the previous build)
  instead of TeX Live 2026's default 1.7, which GitHub's viewer failed
  to load

Stack-1 dad4d3b894 docs: add developer guide internals layer
Introduce docs/internals/ as a two-layer complement to the user manual:
- README.md: index plus the user-manual vs developer-guide rationale
- communication.md: the psb_halo/psb_ovrl -> psi_swapdata dispatch path,
  the psb_comm_handle_type hierarchy and factory, the five MPI schemes
  (isend/irecv, neighbor alltoallv, persistent, RMA pull/push), and the
  start/wait/sync swap-status state machine
