fix(runtime): pass blocks array to destroy_block in reconcile_by_key Map path (#788)

In reconcile_by_key's Map-based path, the fast_path_removal cleanup loop
called destroy_block(a[a_start++]) where `a` is state.array (values).
It should use a_blocks[a_start++] since destroy_block expects a Block object.
Passing a plain value causes a TypeError when destroy_block accesses block
properties (.fn, .p, .f, etc.).
