v0.7.2

Fixes

• All mutations were failing with HTTP 400 (Unknown argument "clientId" on field "Mutation.issueCreate") — Linear's schema removed the top-level clientId argument from issueCreate/commentCreate (May 2026 SDK schema update). Stripped $clientId from all mutation documents and variables; removed the now-dead --client-id CLI flag, MCP clientId param, and CreateIssueParams.clientId.

Tests

• Regression guards assert issueCreate/commentCreate mutations omit clientId from document and variables
• New CI workflow (.github/workflows/ci.yml) runs pnpm test and pnpm run build on push/PR

Chore

• Added lefthook pre-commit (tests) and pre-push (tests + build) hooks
