HexwellandClaude Fable 5 971296f174 refactor: separate libhijacker headers from shared contracts
source/include mixed libhijacker's private implementation headers (util.hpp
with its hand-rolled UniquePtr/String/Vector, plus kernel/, elf/, dbg/,
hijacker/) with genuinely cross-module contracts, and the whole directory was
pulled in as -isystem, so any module could reach libhijacker internals and
every warning in those headers was suppressed.

Move the libhijacker-private headers to source/libhijacker/include and expose
it as a PUBLIC include directory, so the two modules that actually use it —
util for hijacker.hpp, shellui for SHA-1 — now declare that dependency.

Split sha1.hpp: the public-domain SHA-1 goes to third_party/sha1, while
NID_KEY, Sha1 and genSha1 (which needed libhijacker's StringView) move into
the nid.hpp that uses them. shellui only ever wanted the plain digest.

Drop source/include's SYSTEM marker now that it holds only first-party
contracts. That surfaced problems -isystem had been hiding:

  * 68 format-string mismatches in dbg.hpp, printing uintptr_t with %llx
  * freebsd-helper.h redefining PROT_* and TRACEBUF over the SDK's
  * ini.h's header-only helpers declared static rather than static inline

The GNU extensions that TYPE_BEGIN/TYPE_FIELD rely on are now silenced per
header instead of by the blanket -isystem.

Also drop three redundant util.hpp includes (bootstrapper, shellui) that
referenced none of its symbols, and fix backtrace.hpp being included through
relative ../include paths.
