Reverts #10132 (commit c387fc5).

Why

The full-reload fallback added in #10132 did not actually solve the intended problem, so it is being reverted rather than kept as dead complexity. This also removes the extra dev.unregisteredClient test config flag and its snapshot fixture.

The tree after this revert is identical to the state at 99aae0e (the parent of #10132), so nothing else on main is affected.

What is reverted

  • The changed_modules fall-back-to-full-reload path in compute_out_hmr_prerequisites (crates/rolldown/src/hmr/hmr_stage.rs)
  • The dev.unregisteredClient test config flag (_config.schema.json, dev_test_meta.rs, integration_test.rs, dev_engine.rs)
  • The topics/hmr/changed_module_not_executed_by_client snapshot fixture

The underlying issue #10149 remains open for a follow-up.

…not registered as executed (#10132)"

This reverts commit c387fc5.

The full-reload fallback did not actually solve the intended problem,
so it is reverted along with its test fixture and config flag.
