Add support for brace-less hash patterns at top level of case/in.
`in a: x, b: y` is now equivalent to `in {a: x, b: y}`.
`in a:, b:` shorthand now works with newlines (CRuby compatible).
Changes:
- Add EXPR_VALUE to IS_LABEL_POSSIBLE() to recognize labels after `in`
- Add brace-less hash pattern rules to p_expr
- Change p_hash_elem to use p_as instead of p_expr to avoid recursion
- Add in_kwarg flag to parser state for pattern matching context
- Set in_kwarg in lexer when keyword_in is returned
- Use EXPR_ARG after tLABEL_TAG when in_kwarg is set (makes newlines significant)

mruby-compiler
This mrbgem provides the mruby compiler, which is responsible for parsing Ruby code and generating mruby bytecode.
Functionality
The mruby-compiler gem includes the following components:
- Parser: Translates Ruby source code into an abstract syntax tree (AST).
- Code Generator: Traverses the AST to produce executable mruby bytecode.
mrbcexecutable: A command-line tool for compiling.rbfiles into.mrbbytecode files.
Usage
The mrbc (mruby-bin-mrbc) executable will generate compiled binary from Ruby
programs via this gem.
Example of using mrbc:
# Compile a Ruby script to bytecode
bin/mrbc my_script.rb
# Run the compiled script
bin/mruby my_script.mrb
