v1.3.0

Fix migration 0011 pk swap failing on Django 5.0/5.1 + SQLite

On Django 5.0/5.1, RemoveField on a primary key column implicitly re-injects
an auto id field during the SQLite table rebuild, so the subsequent
RenameField(tmp_uuid → id) fails with "duplicate column name: id". Replace
the RemoveField + RenameField + AlterField database operations with a
SeparateDatabaseAndState wrapping a RunPython that does a single explicit
table reconstruction on SQLite, and standard ALTER TABLE DDL on other
databases (PostgreSQL, MySQL). State operations are unchanged.

Bump pymissive and django-pymissive to 1.3.0.

Tested locally against Django 5.0, 5.1, and 5.2 — 144 passed on each.
