Malte UblandClaude Opus 5.5 d06155048e Only bare binding getters are pure; compare getter exports for mutation
A member read in an export getter (a.b or a[b]) can invoke another
accessor that runs code on every read, so the recorder now accepts only a
bare identifier as a plain binding getter. Everything else keeps its
runtime read and is not snapshotted.

The mutation check that makes an earlier island module eager copied only
data properties of a module value, so an object exported through a
binding getter could stay stale when a later load changed it. The shape
now reads binding getters the same way the snapshot does, and compares
them by reading again, so those modules no longer defer.

Corpus fixtures pin both: a getter that reads a member counts every read,
and a later load that mutates a getter-exported object keeps both modules
eager.
