…1697) Adds wire-byte audit for server-side filter rules (filter / exclude / include / exclude from / include from in oc-rsyncd.conf module sections) during a pull. Headline finding: no active divergence today; daemon rules are applied process-locally and never serialised. Documents the load-bearing invariants and divergence sentinels. Companion to docs/audits/tcpdump-daemon-proto28-29.md (PR #3513) and docs/daemon/filter-precedence.md (PR #1888).

Summary
Adds
docs/audits/tcpdump-daemon-server-side-filter-pull.md, a wire-byte audit comparing upstream rsync 3.4.1 with oc-rsync as a daemon serving a pull when the module has server-side filter directives (filter/exclude/include/exclude from/include frominoc-rsyncd.conf).Headline: No active wire-byte divergence today. Daemon-side filter rules are applied process-locally on the sender side as the file list is built; they never traverse the wire in either upstream or oc-rsync. The wire surface for phases 1-8 and 11 is byte-equivalent to a daemon configured with no filter directives. Phases 9-10 differ only by absence of filtered entries, with framing unchanged.
Scope
oc-rsyncd.confonly; client-side CLI filters are covered bydocs/audits/tcpdump-daemon-filter-pull.md.Tracker
Closes #1697.
