build(release): bump version to v0.7.0

[mmols]

Summary

Release PR for v0.7.0

Changes

Added

• Supporting services (beta) — Deploy supporting services alongside databases. This release includes the pgEdge Postgres MCP Server, with automatic database credential provisioning, high-availability connection routing, and declarative configuration.
• Added patroni_port to the database and instance APIs.
• Added ability to configure per-component log levels.
• Added a default value for the host_id configuration setting. It will now default to the short hostname (hostname -s) of the host machine.
• Added guided walkthrough with GitHub Codespaces support.
• Added support for Postgres 16.13, 17.9, and 18.3. Default version is now 18.3.
• Added stop/start instance operations to the client library.
• Etcd mode reconfiguration — Hosts can now switch between etcd server and client modes at runtime, with support for host identity changes via peer URL updates.
• Scoped tasks and new task endpoints — Tasks are now scoped to databases and hosts, with new list/get endpoints for better observability. The remove-host API now returns a task for tracking removal progress.
• Stable random port assignments — Randomly assigned ports now persist across instance restarts and database updates.

Changed

• Improved disaster recovery — Better quorum loss handling, host removal resilience, and crash recovery.
• Breaking: Replaced hostname and ipv4_address fields in the API with peer_addresses and client_addresses for host endpoints and addresses for instance and service instance endpoints.
• Breaking: Replaced server_url (string) with server_urls (string array) in the cluster join token, allowing multiple server URLs when joining a cluster.

Fixed

• Fixed a bug that prevented database deletion when we failed to create the Swarm service.
• Replaced fixed 100-second sync wait when adding a node with configurable health-based polling.
• Fixed sync event refresh blocking updates when Spock node is not configured.
• Fixed panics during task and workflow cancellation.
• Fixed add-node failing silently when Spock sync event is not confirmed.
• Fixed incomplete server shutdown that could leave the workflow engine running without required services.
• Fixed stale resource state blocking updates.
• Fixed IPAM subnet exhaustion after repeated database create/delete cycles by releasing subnets on network deletion.

- Line 398: The example command uses the RC tag 'v0.7.0-rc.1' but this PR is the
GA release; update the example to use the GA image tag by replacing
'v0.7.0-rc.1' with 'v0.7.0' in the make update-lima-fixture command (or, if you
intend to show an RC-only example, explicitly annotate the line as RC-only and
keep both variants), so the command shown (make update-lima-fixture
FIXTURE_CONTROL_PLANE_IMAGE='ghcr.io/pgedge/control-plane:...') reflects the
correct release tag.
