feat(native): port Gleam extractor to Rust (#1105)

* feat(native): port Gleam extractor to Rust

* fix(gleam): use named_child to skip anonymous punctuation tokens

Replaces child(0) fallbacks in handleCall / handle_call with
named_child(0) in both the native Rust and WASM/JS Gleam extractors.

The Gleam tree-sitter grammar's field_access node includes the '.'
punctuation token as a child, so child(0) on field_access could
return '.' as the receiver text on malformed input. named_child(0)
skips anonymous tokens and is consistent across both engines.

The field accessors always succeed on valid Gleam, so this only
affects the defensive fallback path, but it removes a silent
asymmetry that Greptile flagged in review of #1105.

* fix(gleam): match both function_call and call nodes for parity with JS (#1105)

* fix(gleam): align alias fallback with JS extractor and add aliased import test (#1105)

* test: add explicit .gleam assertion to NATIVE_SUPPORTED_EXTENSIONS test (#1105)
