Fix typed user method precedence over void builtins

[luisleo526]

Summary

• resolve exact typed user methods before drawing, array, matrix, and map builtin void-terminal classification
• preserve genuine builtin void-terminal default-return lowering
• cover direct and namespace-shadowed drawing, array, and map receivers plus terminal if and switch paths

Verification

• focused candidate: 10/10
• broader receiver, terminal, and drawing cohort: 420/420
• full explicit-corpus suite: 2510 passed, 1 skipped; sole skip is the established parser NOTSET case
• 685-source base/candidate differential: 680 successes and the same 5 failures on each side; zero status, diagnostic, or generated-C++ changes
• engine corpus: 252/252, board 247 Excellent / 4 Strong / 1 anomaly; report self-test 252/252
• forced-no-cache scraper gate: 416/416 classified; 409 OK, 1 no-trades, same 5 transpile errors and 1 run error, zero compile/driver/timeout failures
• scraper board unchanged: 355 Excellent / 46 Strong / 4 Moderate / 2 Weak plus 7 excluded; 0 up / 0 down
• independent diff review: PASS
• git diff --check: PASS
