v0.1.1

[0.1.1] — Unreleased

Fixed

• Foreground taskflow runs silently executed no phase (issue #3, broadest
  impact — found during the regression sweep). The same default-runner change
  that broke detached runs also broke runFlow (every foreground run) and both
  recomputeTaskflow paths in pi-taskflow/src/index.ts: they constructed
  RuntimeDeps without a runTask, so every phase hit the noRunnerInjected
  stub. Pre-refactor this worked only because the engine's default runTask
  was runAgentTask (same package). Fixed by explicitly injecting
  piSubagentRunner.runTask at all three call sites. Added a structural
  regression test that scans the production source and fails if any
  executeTaskflow/recomputeTaskflow deps omits runTask.
• Detached (background) runs crashed on launch (issue #3). The detached
  runner specifier resolved to dist/detached-runner.js.js (double .js) under
  taskflow-core's "./*" export rewrite, so the spawned child died at import
  with Cannot find module. Now resolved with a suffix-less specifier
  (taskflow-core/detached-runner) → dist/detached-runner.js. The stale
  --experimental-strip-types flag (the runner ships compiled) is dropped.
• Detached runs could never execute any phase (issue #3, deeper). The
  detached-runner called executeTaskflow with no runTask (see the default
  above), so every detached phase failed with "No subagent runner injected" even
  after the module loaded. Fixed: the host serializes a runnerModule/
  runnerExport (resolved from its own package, works under both workspaces and
  npm installs) into the detached context file, and the detached-runner
  dynamically imports it and injects runTask.
• A crashed detached runner no longer leaves the run stuck at running
  forever (issue #3, secondary). The host now pipes stderr and attaches
  exit/error handlers that, when the child dies before reaching a terminal
  state, persist status: "failed" with the captured stderr recorded in a
  pollable synthetic phase (__detach__). Race-safe: guarded by pid + status so
  a genuine terminal state the runner persisted is never clobbered.
