Original formatter dispatch integer string character and literal composition

RE-815. Reproduce with python3 scripts/analyze_qvm_formatter.py; focused validation: cargo xtask test-group formatter. Machine report.

55 complete source formatter fixtures cover d/i/p, string width/precision/null handling, zero and left padding, escaped percent, raw characters, unknown conversions and mixed arguments. Independent parsing/byte arithmetic verifies result length and terminal NUL, including embedded character NUL. Float formatting, malformed/trailing formats and unsafe vararg/padding domains remain excluded.

Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified.
