Add single-byte opcodes for returning true/false directly, completing
the set of literal return opcodes (RETSELF, RETNIL, RETTRUE, RETFALSE).
Codegen applies peephole optimization to fuse LOADTRUE/LOADFALSE + RETURN.

Add a new opcode that returns nil without requiring LOADNIL + RETURN.
This avoids loading nil into a register by setting the return value (v)
directly. The implementation uses a separate label (L_RETURN_NIL) to
bypass v = regs[a], preserving self in regs[0] for ensure blocks.

Bypass method dispatch when calling blocks via yield. The new OP_BLKCALL
instruction directly invokes the proc without looking up Proc#call,
resulting in 13-17% faster yield performance.

Ran `pre-commit run --all-files --hook-stage manual` and this ran prettier.
We had a Markdown table reformated and an backslash escape added.
A link was also fixed.
Tested both the standard and manual hooks pass
