chore: remove pgmq version constraint (#283)

# Remove PGMQ Version Constraint

This PR removes the version constraint for the PGMQ extension in both the core schema and Supabase migrations. By removing the explicit version requirement (`version '1.4.4'`), we allow the database to use the latest available version of PGMQ.

The changes affect:
- `pkgs/core/schemas/0010_extensions.sql`
- `pkgs/core/supabase/migrations/20250429164909_pgflow_initial.sql`
- Updated the `atlas.sum` file to reflect these changes

This approach provides more flexibility for PGMQ version management and avoids potential compatibility issues when newer versions are available.

+Fix installation failures on new Supabase projects by removing pgmq version pin.
+
+Supabase upgraded to pgmq 1.5.1 in Postgres 17.6.1.016+ (https://github.com/supabase/postgres/pull/1668), but pgflow was pinned to 1.4.4, causing "extension has no installation script" errors on fresh instances.
+
+Only affects new projects - existing installations are unaffected and require no action.

+
+pgflow 0.7.1 fixes installation failures on fresh Supabase projects caused by pgmq version mismatch.
+
+<Aside type="note" title="Existing Projects Unaffected">
+If you already have pgflow installed, you're completely unaffected. This fix only impacts fresh installations on new Supabase projects. No action needed, no code changes, and no need to update to 0.7.1.
+</Aside>
+
+## The Bug
+
+Installing pgflow on new Supabase projects failed with:
+
+```
+ERROR: extension "pgmq" has no installation script nor update path for version "1.4.4" (SQLSTATE 22023)
+At statement: 2
+CREATE EXTENSION IF NOT EXISTS "pgmq" WITH SCHEMA "pgmq" VERSION "1.4.4"
+```
+
+## Why It Happened
+
+Supabase upgraded to pgmq 1.5.1 in Postgres 17.6.1.016+ ([supabase/postgres#1668](https://github.com/supabase/postgres/pull/1668)). pgflow's initial migration was pinned to version 1.4.4, which no longer exists in new Supabase instances.
+
+## The Fix
+
+Removed the version constraint from pgmq extension creation. pgflow now uses whatever pgmq version Supabase provides (1.4.4, 1.5.1, or newer).
+
+```diff lang="sql"
+-CREATE EXTENSION IF NOT EXISTS "pgmq" WITH SCHEMA "pgmq" VERSION "1.4.4";
++CREATE EXTENSION IF NOT EXISTS "pgmq" WITH SCHEMA "pgmq";
+```
