Refactor _term() by extracting _term_ident(), _term_array_literal(), _term_paren() [SRP]

_term() was ~130 lines mixing literal push, array literal construction,
identifier resolution, parenthesized expressions, and defined/undef/syms.

Extracted three static helpers:
- _term_ident(): resolves TT_IDENT as array access, builtin call,
  self-defined function/proc call, or variable/procedure (~90 lines;
  acceptable given the complexity of identifier resolution)
- _term_array_literal(): builds an array from [expr, ...] syntax
- _term_paren(): evaluates a parenthesised expression and checks ')'

_term() is now a ~100-line dispatcher. The defined/undef/syms cases
remain inline as they are self-contained ~10-line blocks.

Also fixes a latent double-assignment bug in _term_array_literal():
the original `TokenType tt = tt = p_interpret->tt;` is now `= p_interpret->tt;`.
