Code Review — PR #1048 feat(a2a): implement SSE streaming

(Note: Cannot submit formal review approval since this PR is authored by the same account. Leaving review as a comment instead.)

The implementation is technically sound — SseEventFormatter, EventBusBridge, and the domain-to-A2A event mapping are clean and well-tested with 8 Behave scenarios.

Process Issues

  1. Empty PR body — Per CONTRIBUTING.md §Pull Request Process, every PR must include a clear description with summary, issue reference, and dependency link. Please add a proper description.

  2. No linked issue — This feature addition should reference its tracking issue with a Closes #NNN keyword.

Minor Code Notes

  1. Inline import — import contextlib is imported inside the _on_domain_event method body rather than at the module top level. Per the project's import guidelines: "Ensure all imports are at the top of the Python file."

  2. Silent error suppression — contextlib.suppress(RuntimeError) when publishing to the queue silently swallows all RuntimeError variants. Consider at minimum a debug-level log so that publish failures are traceable.

  3. default=str in JSON serialization — SseEventFormatter.format() uses json.dumps(data, default=str) which silently converts any non-serializable type to its string representation. Pragmatic but could mask data type issues — worth a code comment.

PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

 auto/driver-down
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.
 auto/invariant-violation
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.
 auto/last-attempt-tier-0
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

 auto/last-attempt-tier-2
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.
 auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

 auto/needs-conflict-resolution
Rebase conflict needs LLM conflict-resolver.
 auto/needs-implementer
Failing CI needs implementer attention.
 auto/postmortem
Documenting a driver incident or rollback.
 auto/ready-to-merge
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.
 auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.
 auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.
 auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.
 auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.
 auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
 Blocked
A ticket in a blocked state and unable to complete until some other task is completed first.
