02 — Complete backtick command lexing and parsing

Status: resolved Blocked by: #01 Blocks: #03

Backtick lexing is partially implemented:

llex.c: TK_COMMAND token lexed via read_string() on backtick
llex.h: TK_COMMAND enum added
lparser.c: TK_COMMAND handled in simpleexp() (as string) and suffixedexp() (as func args)

Remaining work

Verify the lexer handles edge cases (escaped backticks, newlines, nested quotes)
Parser must emit code that produces a result table ({code, stdout, stderr}) at runtime, not just a string literal
May need a new opcode (e.g. OP_COMMAND) or compile as a call to a built-in execution function
Add string interpolation inside backticks if decided in #01

Files touched

llex.c / llex.h
lparser.c
Possibly lopcodes.h / lopcodes.c if adding a new opcode
