fix(docker): pin doltgresql image to 0.56.7 across template and dev c…

[Adityakk9031]

Summary

Fixes #3465 where running npx @inkeep/create-agents or pnpm setup-dev failed during project seeding / inkeep push with HTTP 500 (SELECT * FROM dolt_tags caused by error: role "appuser" does not exist).

Root Cause

While root docker-compose.yml explicitly pinned dolthub/doltgresql:0.56.7, template and local development docker-compose files used unpinned dolthub/doltgresql:latest with pull_policy: always. Recent upstream builds of dolthub/doltgresql:latest introduced a wire-protocol session authorization regression when queried over host-port forwarding proxies (e.g. localhost:5432 on Docker Desktop), breaking dolt_tags / dolt_branches queries for host-bound Node services.

Changes

1. Pinned Doltgres Docker Image:

   • create-agents-template/docker-compose.db.yml
   • create-agents-template/docker-compose.yml
   • docker-compose.dbs.yml
   • docker-compose.isolated.yml
     Updated image from dolthub/doltgresql:latest to dolthub/doltgresql:0.56.7 and removed pull_policy: always.

2. Added Changeset:

   • Added patch changeset for @inkeep/create-agents in .changeset/pin-doltgres-image-tag.md.

Verification

• Verified that all compose files now consistently reference dolthub/doltgresql:0.56.7 matching root docker-compose.yml.
• Verified changeset resolution for published template package.
