Contain static response disconnects at the Node transport boundary

[smiggleworth]

Summary

Closes #38

The Node static asset adapter now treats client disconnects as transport cancellation, tears down the file source through the pipeline callback, and leaves the server available for later requests. The review fix removes the ineffective synchronous try/catch and handles pipeline errors in the callback.

Public API and compatibility

• Releases @askrjs/node 0.2.2 from 0.2.1.
• No public API, peer range, or runtime compatibility contract changes.
• The lockfile advances only the eligible first-party @askrjs/server patch from 0.2.1 to published 0.2.2.
• @types/node 26.4.0 is excluded to retain the required 26.3.x line. No major or minor dependency changes, aliases, workarounds, or security work are included.

Validation

• Clean npm ci: 108 packages, 0 vulnerabilities.
• The real Node HTTP disconnect regression passed three consecutive focused runs.
• Full npm run check passed: 3 test files / 63 tests, type checks, build, publint, and packed-artifact validation.
• Hosted CI passed on Ubuntu, macOS, and Windows for e417b1b.
• The complete main-to-head diff received a second review after remediation.
• The only review thread is answered and resolved; local HEAD, upstream, and PR head match.
