fix(ci): merge smoke-test release phase 2 into repository dispatch

[c-vigo]

Description

Merges smoke-test release phase 2 back into repository-dispatch.yml so downstream release.yml runs while release/<version> still exists (fixing the branch-not-found failure). Removes the separate on-release-pr-merge.yml workflow. Updates Bats coverage for the smoke-test template layout.

Type of Change

• feat -- New feature
• fix -- Bug fix
• docs -- Documentation only
• chore -- Maintenance task (deps, config, etc.)

Changes Made

• assets/smoke-test/.github/workflows/repository-dispatch.yml — absorb phase 2: run release.yml while release branch exists, then enable auto-merge and poll for merge completion
• assets/smoke-test/.github/workflows/on-release-pr-merge.yml — removed (logic merged into dispatch workflow)
• CHANGELOG.md and assets/workspace/.devcontainer/CHANGELOG.md — document fix under 0.3.1 Fixed
• tests/bats/just.bats — align expectations with updated smoke-test workflow files

Pull request overview

This PR fixes the smoke-test release “phase 2” branch-not-found failure by moving the downstream release.yml dispatch/wait logic back into the main repository-dispatch.yml orchestration so the release workflow runs before the release/<version> branch is merged/deleted.

Changes:

• Add trigger-release and merge-release-pr jobs to the smoke-test repository-dispatch.yml to run release.yml, then enable auto-merge and wait for the release PR to merge.
• Remove the separate smoke-test workflow on-release-pr-merge.yml (phase 2) since its logic is now in repository-dispatch.yml.
• Update changelog entries and adjust Bats assertions to reflect the new workflow layout.
