fix: all 317 SCI forms load, zero failures

- Reorder load sequence: types→unrestrict→vars→lang→utils→namespaces→core
- Add if-let/when-let/if-some/when-some/let macros and register in core-macro-names
- Add stubs: resolve, update, copy-core-var, copy-var, macrofy, new-var, avoid-method-too-large
- Add dynamic vars: *1, *2, *3, *e, *assert with nil-sentinel
- Fix core-update: use put instead of Janet's update (struct-incompatible)
- Change *clojure-version* from struct to table (mutable for update)
- Fix core-avoid-method-too-large: return @{} not nil
- Fix init-core! nil-sentinel unwrapping
- Fix let* destructuring for {:keys [...]} and sequential patterns
- Fix fn*/defmacro: capture defining ns for symbol resolution in closures
