Cache lookup fails above wincode's 4 MiB preallocation limit #557

Description

@wan9chi

Error

A task-cache lookup fails for a cache entry with 77,885 inferred inputs:

Cache lookup failed: Encoded sequence length exceeded preallocation limit of 4194304 bytes (needed 4361560 bytes)

Root cause

wincode 0.5.2 allowed the task-cache encoder to write this inferred-input map, then rejected the same map while decoding it. The decoder estimated 4,361,560 bytes of sequence preallocation against the default 4,194,304-byte limit.

The task cache used wincode's default configuration, so a large valid cache entry could become unreadable after Vite+ wrote it.

Expected behavior

The task-cache codec should use a cache-specific preallocation limit that supports large inferred-input sets on both encode and decode.
