on_build is now the sole post-build callback mechanism. Migrated the 9 callers (0602/0603/1611/1614/1615/1616 + the platform bundle_main) from opts.set_post_link_callback(cb) to on_build(cb), giving each callback the (opt: BuildOptions) param. Deleted set_post_link_callback from build.sx, compiler_lib (bound_fns + handleSetPostLinkCallback), and the VM arm. Reworked the P5 smoke tests for the new semantics: an on_build override REPLACES the build (must emit+link or delegate), unlike the old post-link callback which ran after the auto-link. 1662 (queries) + 1664 (override+List-grow) now delegate to default_pipeline for the real build; deleted 1661/1663 (the primitives are now exercised by every AOT build). bundle_main invoked with pass_options=true. Benign 37-.ir churn (build.sx shrank). 703/0 both gates.
