Add PBS find-references as the request-local inverse of definition
identity on FrontendLanguageService. Usage sites are identifier
tokens whose definition locations intersect the cursor set.
Empty results stay honest when definition is empty, including
virtual stdlib paths. Honor includeDeclaration in the LSP bridge.
Housekeep DSC-0040 with LSN-0069.
Add PBS go-to-definition as hover editorial lookup plus physical
declaration locations on FrontendLanguageService. Empty results stay
honest when the target is not a regular file, including virtual stdlib
paths.
Housekeep DSC-0039 with LSN-0068.
Add a test-only synth FrontendProvider that traverses compile() to
verified bytecode without PBS. Expose register/unregister on the static
registry and lock the obligation in specs 23 and 22.
Housekeep DSC-0063 with LSN-0065.
Move lifecycle assembly out of the PBS frontend into a common
AssembleLifecyclePipelineStage. PBS emits a typed IRLifecycleDeclaration;
the assembler owns wrappers, boot guard, and single project-init execution.
Housekeep DSC-0059 with LSN-0062, and include the DSC-0062 PVM/PBX
neutrality spec and lesson already present on this branch.
