Rename project from wireframe to packeteer
Decided on the name after weighing alternatives in NAMES.md: packeteer
(packet + -eer, "one who wields packets") fit the project's actual
scope better than the wire/frame pun once it had grown into full
L2-L7 dissection, reassembly, checksums, privilege dropping, and dual
TUI/GUI frontends. No existing packet-capture project uses the name;
the one real-world collision (Packeteer, Inc., a networking company
acquired and folded into Blue Coat/Symantec by 2008) is long defunct.
Mechanical rename throughout: CMake project/target names, the
wireframe:: namespace and include/wireframe/ directory (git mv,
history preserved), every #include path, CLI/GUI help text, and the
project's own working directory. NAMES.md rewritten to record the
decision instead of leaving stale self-referential etymology behind
from the blind rename pass.
Verified after every step: full rebuild (all four targets, no
warnings) and the full test suite (128/128 cases, 366/366 assertions)
both from a fresh reconfigure and again after the directory move.
