Malte UblandClaude Opus 5.5 06e987b848 Skip the record-source lookup in typed JSON.stringify unless one was kept ...

Every closed record written by a typed JSON.stringify called
scr_jb_try_record_source first, an out-of-line call and table probe for
records that almost never keep a source (2% of json-records samples).

The record writer now tests the record-sources constant first, so a
program without a checked conversion that can keep a source emits no
lookup. Where one can, the writer tests the dispose hook inline before
calling: keeping a source installs the hook, so a NULL hook means the
table is empty, and only a program that has kept a source pays the call.
