OpenCode MCP Bridge v0.3.0

Added

• New worker_wait tool (requires v0.3.0 code): bounded server-side
  long-poll for one task. Returns on state or message change, or at the
  finite timeout_s deadline (default 30, clamped 1-120) with
  timed_out=true and next_action="worker_wait". Read-only with
  include_output=false state-only waits; no client sleep loops.
  Served on /worker-mcp (now six worker tools) and /mcp (now
  17 tools); auto-approved alongside worker_status, worker_catalog,
  and worker_verify in .mcp.json.
• Stable additive task contracts: worker_run, worker_wait,
  worker_status, worker_verify, worker_cleanup, and
  worker_catalog keep every existing key and add state, timed_out,
  retryable, next_action, error_code (for example task_not_found
  for a missing task, else null), and a concise evidence object.
  Existing clients keep working. Truthful output_schema on every
  worker tool, including the full status field set on worker_verify.
• Deterministic MCP conformance smoke tests
  (tests/test_mcp_conformance.py): handshake negotiation, exact
  6/17 tool surfaces, truthful wire schemas and annotations,
  free-first catalog recommendations, dedup, error/scope behavior,
  and bounded output. Focused worker_wait tests
  (tests/test_worker_wait.py) prove bounded waits, read-only
  behavior, and backward-compatible status contracts.
• Harness and adoption documentation: coordinator-ergonomics README
  section, worker_wait-first workflow in docs/tool-api.md, skills
  (delegate-to-opencode, recover-opencode-task,
  coordinate-opencode-worker) preferring bounded worker_wait with
  worker_status snapshots and the worker_verify evidence gate, and
  a six-tool scripts/smoke.sh.
• Published plugin versions: Codex opencode-worker 0.3.0
  (.codex-plugin/plugin.json, marketplace ref v0.3.0) and Claude
  opencode-worker 0.3.0
  (plugins/claude-code/.claude-plugin/plugin.json,
  .claude-plugin/marketplace.json). Bridge and registry metadata
  (pyproject.toml, server.json) track 0.3.0.

Models: free Muse Spark 1.3 default with paid fallback only when explicitly chosen.
