Commit: text tiers: a literal bound by a let is declared String, never a String? taken from the program (#943)
Body: The cause was not the tools profile: any String? field, parameter or result in a file (the first written String node string_type found, plain_string ignoring nullability) became the type of every let of a literal kept as text, so let mut out = "a" was String?; nikaia run fails the same once the program has a String?. string_type now skips nullable nodes.
Fixes: #943
Pushed: 417fc0476da144edb8bbfd2b62704e82c6d401ff
Tests: new test fails on the unfixed compiler (NK1125+NK1104), passes now; tests/compiler –both-settings 248 ok, 1 failed (fmt_keeps_a_nested_tuple_closure_whole, from 7c1643d: prints 1 without newline, .stdout has one); it nullable:: text_tiers, range_spelling, shipped_ledger, contracts::every_std_module, dependency_ledger, fmt::every_nika_file ok; probe put into scratch tools/modules.nika passed lower-std, restored by name; clean lower-std changes only lowered/text_tiers.rs; clippy clean; pre-push-check ok
Gate: green

Found: tests/compiler/tests/fmt_keeps_a_nested_tuple_closure_whole fails (print without newline vs .stdout “1\n”, 7c1643d)

Changelog: A literal bound with let is no longer typed String? when the program writes a String? anywhere (#943).
