feat(observer): opt-in zend_extension hooks via typed builder

Add `ModuleBuilder::zend_extension(factory)` returning a `ZendExtensionBuilder`
with `hook_statements()`, `hook_fcalls()`, and `hook_op_array_compile()`
opt-ins. Only opted-in hooks are wired to PHP and only their matching
ZEND_COMPILE_* flags are set, so unused hooks cost nothing at compile time.
Compiler flags are also re-asserted in `on_activate` for ZTS worker threads.

Internal wiring now goes through `CompilerGlobals::get_mut()` and a pub(crate)
`zend::register_extension()` helper rather than raw ffi from the feature
module.
