Ivan Porto Carrero 9e2bb92895 fix(arena): NULL-arena guard in cbm_arena_alloc; skip vendored/ dirs ...

- cbm_arena_alloc returns NULL on a NULL arena (both arena.c copies)
  instead of dereferencing it — defense-in-depth against the NULL-arena
  type-allocation path that could crash the LSP type layer.
- discover: add "vendored" to the always-skip directory list.

Distilled from #374, taking the parts not already on main. The PR's
ts_lsp tuple-arena allocation, the C/C++ template formal-count clamp,
and the type_rep unbound-param preservation it also carried all landed
independently in v0.7.0 / via #322 / #360, so only these two
defensive improvements remain. Relates to #390.
