jjoos 4d84406921 fix(extraction): convert fixed-size stacks in extract_channels.c to growable TSNodeStack ...

The 8 channel-extraction DFS walkers (Python consts, Python, Go, Java,
C#, Ruby, Elixir, Rust) used fixed-size `TSNode stack[CHAN_STACK_CAP]`
arrays whose push loops guarded with `&& top < CHAN_STACK_CAP`. On
deeply-nested ASTs that guard silently dropped children, and an
unguarded overflow could corrupt adjacent stack memory — surfacing as a
segfault in a later pass (lsp_cross / semantic_edges) on large repos.

Convert all 8 to the arena-backed growable TSNodeStack
(ts_nstack_init/push/pop), matching the pattern already used in
extract_calls.c / extract_imports.c (PR #217). No silent drops, no
overflow.

Distilled from #339 (trailing-newline cleanup only; conversion is the
author's).
