Public-flip audit: generalize internal hosts/paths + drop Sulkta-internal refs

URLs, mount paths, and LAN host bindings parameterized via env or relative paths
so the repo stands up from a clean clone anywhere. Drop cross-codebase refs
("mirrors clawdforge's pattern"), Sulkta-Coop client/merchant test fixtures,
and audit-changelog scaffolding from comments. README terser, technical content
preserved.
