P5.4: migrate all callers to on_build; delete set_post_link_callback

Browse Source 
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.

// P5.3 smoke test — `on_build(build)` registers the build callback (the Phase 5
// form), and the compiler invokes it post-codegen WITH the BuildOptions handle
// as an arg (`build :: (opt: BuildOptions) -> bool`). This exercises the VM
// entry that passes an explicit arg after the implicit context (runEntryArgs).
// The callback uses the build-pipeline primitives (no opt accessors yet) and
// returns true; AOT observes success via the build exit code.
// P5.4 — the `on_build` override. A user `#run on_build(build);` replaces the
// stdlib `default_pipeline` as the build driver; the compiler invokes it after
// codegen with the `BuildOptions` handle. This build GROWS a `List` on the build
// VM (comptime List growth works only on the VM — issue 0141; the legacy interp
// fails it) then DELEGATES to `default_pipeline` for the real emit + link, so a
// working binary is still produced → "runtime main".
