Resolves the schema-version collisions this branch hit against main:
- parse-cache SCHEMA_BUMP: branch had 32, main took 32 (#2742) and 33/34
(#2747) first -> renumbered to 35, keeping main's v32-v34 notes.
- INCREMENTAL_SCHEMA_VERSION: branch had 25, main advanced to 28 ->
renumbered to 29, keeping main's v25-v28 notes.
- Pin tests updated to the new numbers; the reuse-gate test now rejects a
v28 stamp (no Class->CodeElement relation schema for @Bean INJECTS).
