Claude (auto-RE) 33a7bf836b perf(mesh): memoise the whole-container decode ...

Filtering after the assignment made every subset query a full decode (~15s on a
50MB container). full_decode_cached memoises it per container -- fingerprint is
length plus three sampled 4KB windows, keyed with min_consistency, last four kept.
Decoding five ships from Stage_S02 in turn: 10.5s for the first, then 48us-1.4ms.
A stage now costs one decode rather than one per ship. Ten suites green, viewer
builds, and a spot-checked resource still lands on the same offset.
