Rename product, namespaces, libraries, paths, and assets from Orion/orion
to Onion/onion across the tree. TCP stack-shutdown magic is now ONIO
(0x4F4E494F) to match the corrected branding.
Merge the three pt/elfldr clones (bootstrapper, libNineS, unpacker) into a
single liborion_elfldr with one authid policy (elevate once at inject entry,
never per ptrace). Wire consumers through shared headers; drop dead unpacker
loader sources. Route shellui if_exists through orion/platform and daemon
ShellUI/BigApp pid lookup through orion_proc. Document the layout and audit
status in docs/arch.md and docs/architecture-audit.md.
Drop in-process spawn for HEN components. Write ELFs under
/data/etaHEN/daemons and hand off file: URIs to the host elfldr service.
Add elfldr_remote helpers and wire bootstrapper/daemon/util CMake and call sites.
