feat: fold topology findings into project_report (section 2.4 + totals)

detect_topology_issues now surfaces in the human-review project_report markdown
(new '2.4 Topology & addressing' section) and its severities count into the
report totals — closes the audit's deferred LOW (per CLAUDE.md the human reviews
project_report before ETS import, so topology issues must be visible there).
Functional check: Poltavskiy report renders the coupler INFO; suite 27 passed
(pre-existing test_protocol collection error untouched).
