Merge pull request 'fix(a2a): handle string error in a2a_tools + remove dead staging trigger' (#281) from fix/a2a-tools-and-workflow-cleanup into main

[core-lead-agent] PR #281 merged — handles string-form errors in a2a_tools.delegate_task (was raising AttributeError on every delegation through legacy path), fixes empty-parts dict regression (#279), and drops the dead staging branch trigger from both publish workflows. Replaces the abandoned PR #268 + #277. Integration Tester unblocked for mesh recovery validation.

+#   - Gitea Actions reads .gitea/workflows/, not .github/workflows/
+#   - Dropped `environment: pypi-publish` — Gitea Actions does not support
+#     named environments or OIDC trusted publishers
+#   - Replaced `pypa/gh-action-pypi-publish@release/v1` (OIDC) with
+#     `twine upload` using PYPI_TOKEN secret — same mechanism as a local
+#     `python -m twine upload` with a PyPI token
+#   - Replaced `github.ref_name` (GitHub-only) with `${GITHUB_REF#refs/tags/}`
+#     — Gitea Actions exposes github.ref (the full ref) but not ref_name
+#   - Dropped `merge_group` trigger (Gitea has no merge queue)
+#   - Dropped `staging` branch trigger (no staging branch exists in this repo)
+#
+# PyPI publishing: requires PYPI_TOKEN repository secret (or org-level secret).
+# Set via: repo Settings → Actions → Variables and Secrets → New Secret.
+# The token should be a PyPI API token scoped to molecule-ai-workspace-runtime.

+# Gitea Actions port of .github/workflows/publish-workspace-server-image.yml.
+#
+# Ported 2026-05-10 (issue #228). Key differences from the GitHub version:
+#   - Gitea Actions reads .gitea/workflows/, not .github/workflows/
+#   - Dropped `environment:` declarations — Gitea Actions does not support
+#     named environments (used by GitHub OIDC token gates)
+#   - Replaced `github.ref_name` (GitHub-only) with `${GITHUB_REF#refs/heads/}`
+#     — Gitea Actions exposes GITHUB_REF in the same format as GitHub Actions
+#   - docker/setup-buildx-action and aws-actions/configure-aws-credentials are
+#     GitHub Marketplace actions; they are installed by Gitea Actions runners and
+#     work identically here
+#   - All other variables (GITHUB_SHA, GITHUB_REPOSITORY, GITHUB_OUTPUT,
+#     secrets.*) use the same syntax as GitHub Actions
+#
+# Image tags produced:
+#   :staging-<sha> — per-commit digest, stable for canary verify
+#   :staging-latest — tracks most recent build on this branch
+#
+# ECR target: 153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/*

+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
