Fix: Migration Autodetector class mismatch errors with dynamic command inheritance

[erdem]

Before continue to read this PR description first get initial context from this public PR.

What We Tried First (in the public PR)

INSTALLED_APPS = [
    "django_linear_migrations",  # First
    "django_pgviews",             # Second
    ...
]

Why It Failed

Django loads management commands from INSTALLED_APPS in order. The first app providing a command wins, later apps with the same command are ignored.

However:

django_linear_migrations makemigrations command module overrides django_pgviews makemigrations command module. Django sees django_linear_migrations provides makemigrations first and uses that. django_pgviews command implementation never even imports or runs and PGViewsAutodetector class modification to the original command is never applied.

---

Our Solution

INSTALLED_APPS = [
    "django_pgviews",            # First - ensures our commands load
    "django_linear_migrations",   # Second - we'll inherit from it
    ...
]

Why This Works

1. Changed break → continue: Now our lookup skips django_pgviews but continues checking apps after us in INSTALLED_APPS
2. Finds django_linear_migrations: When we iterate through apps, we hit django_linear_migrations (after us) and successfully import its command class
3. Inheritance chain: Our command inherits from django_linear_migrations's command, which inherits from Django's, preserving both:
   • PGViewsAutodetector (from us)
   • max_migration.txt tracking (from django-linear-migrations)

---

The Risk

Normally, apps later in INSTALLED_APPS override earlier ones. With django_linear_migrations after django_pgviews, if django_linear_migrations provided both makemigrations and migrate commands, it would override ours completely and break pgviews.

Why It's Safe

django_linear_migrations only provides makemigrations command (not migrate). Since Django's command loading sees our commands are already loaded and django_linear_migrations doesn't override all of them, our commands remain active while successfully inheriting from theirs.

---

The Comment Explains It

# Must follow django_pgviews: pgviews dynamically inherits from commands loaded
# before it, preserving both PGViewsAutodetector + max_migration.txt tracking

We're essentially saying: "Load us first so we control the final commands, but we'll look ahead and inherit from apps that come after us."
