v0.4.2

Release v0.4.2

Rate-limit resilience + API usage diagnostics improvements.

Highlights

• Improved linear_issue update behavior when Linear rate limits occur after successful mutation
• Added in-memory caching for common resolver calls to reduce request volume
• Added optional per-command API usage summary in tool output

Bug Fixes

• Fallback response for post-update refresh rate-limit failures (avoids false operation failure)
• Correct per-command usage delta accounting in diagnostics

Performance / API Usage

• Viewer cache: 30s
• Projects cache: 60s
• Teams cache: 60s
• Team workflow states cache: 60s (per team)
• Direct ID lookup fast-paths for project/team resolution

Diagnostics

• PI_LINEAR_TOOLS_USAGE_SUMMARY=true adds:
  • markdown summary line in tool output
  • details.apiUsage payload for integrations
• Debug logs include request delta per tool action

Notes

• Issue list payloads remain uncached (fresh data from Linear on each list call)
