/**
 * Grow WASM linear memory if needed so `neededBytes` of input (plus the
 * offset reserved for Zig's stack/globals) fits without truncation.
 *
 * Fixed 2026-08-23: writeToMemory() used to silently truncate any input
 * larger than the WASM module's initial memory (~1.06MB usable) BEFORE
 * estimate_tokens ever ran — no error, no flag, just a token count
 * computed over a truncated prefix. This defeated the "never
 * under-report" invariant exactly where it matters most: calls near a
 * model's real context ceiling. WebAssembly.Memory is growable at
 * runtime (confirmed: `memory.grow()` works on this module, 17 pages ->
 * 117 pages tested directly) — growing does not move or invalidate
 * existing data, it only appends new zeroed pages, so this is safe to
 * do lazily on every call with no effect on correctness for small inputs.
