Levi Neuwirth fb4c18e490 T M4.5: default C/C++ (clangd) + Go (gopls) language entries
Two more real languages on the proven async + UTF-16 + config-pull
base. Pure pattern application of the #12 Python shape.

- pmacs.lsp.config.c / .cpp → clangd `--background-index`. One
  binary serves both; separate entries only so the didOpen
  languageId is accurate. No `settings`: clangd's project model is
  compile_commands.json / compile_flags.txt, not
  workspace/configuration (documented in-line).
- pmacs.lsp.config.go → gopls (no args = stdio). settings =
  { gopls = {} } so the #13 workspace/configuration pull is answered
  "use defaults" (present, not null — gopls prefers that).
- pmacs.lsp.filetypes extended: c/h → c (.h defaults to C,
  remappable); cpp cc cxx hpp hh hxx ipp inl cppm → cpp; go → go.
- Two PATH-gated acceptance tests via a shared DRY helper, mirroring
  m4_5_basedpyright: reach Initialized + assert the negotiated
  positionEncoding is one pmacs can encode. Skip cleanly when the
  binary is absent.

clangd is on the dev PATH, so its test ran for real: the full stack
(async bridge + Option B UTF-16 + registry + filetypes) is validated
end-to-end against a real strict-default C/C++ server, closing the
"validate UTF-16 against a real strict server" gap from the Option B
evaluation. gopls test skips here; runs wherever gopls is installed.

Gate: fmt clean; clippy --all-targets -D warnings clean; lib
1230/0; m4_acceptance 64/0 (clangd ran live); m9_1 18/0;
m8_1/m8_9/m8_10 green.
