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 duplicate allproc/ucred sources from NineS. Headers are shims to
orion/*, injector uses get_module_info, and CMake builds orion_proc before
NineS so inject and daemon share one process stack.
Drop unused hello_world ELF blob, sqlite headers/lib, and orphan
demo headers. Replace the 14k SCE error dump with a ~300-entry
install/BGFT table for DPI, cutting ~7MB from the source tree.
Match filename, libname, and sandboxed path basename. Prefer a non-allocating
get_module_info API and fix handle leaks on the successful get_module_handle path.
