Fix function body literal mutation: make examples pass
Two bugs combined to break uber.fy and any function called more than once:
1. Scanner split identifiers at '_' boundaries (e.g. arr_sum → arr + _sum).
Fixed by adding d != '_' to the token-splitting guard condition so
underscores are treated as part of identifiers.
2. Dead keyword TT_ARR reserved the name 'arr' as a keyword token,
preventing its use as a function parameter. Removed TT_ARR from the
enum, keyword table, and name table.
3. (Root cause of the assert failure) _var_assign stored the symbol for a
newly declared variable pointing directly at the literal token from the
function body token list. incr/decr modify tokens in place via
stack_top, so a loop like `my i = 0; while i < n { incr i; }` would
corrupt the body's '0' literal — on the next call i starts at 10 instead
of 0. Fixed by allocating a fresh token_new_integer / token_new_dummy
for TT_INTEGER and TT_DOUBLE initialisers so body literals are never
mutated. Arrays and strings retain reference semantics unchanged.
