Fix Gleam compile script error

- Remove gleam@@compile.erl from erlc paths to prevent compilation errors
- Add gleam@@compile.erl to .gitignore
- Update erlc_paths to only include 'src' directory
- This prevents Erlang from trying to compile Gleam's escript files

The error was caused by Erlang trying to compile a shell script that
starts with #\!/usr/bin/env escript as an Erlang source file.
