Pull request overview

Adds the promise/avoid-new rule to the promise plugin, aligning behavior (and baseline tests) with eslint-plugin-promise rule avoid-new as part of the #474 rule-porting effort.

Changes:

• Implement promise/avoid-new rule logic (report new Promise(...) when callee is the identifier Promise, matching upstream behavior).
• Add upstream-aligned and extra edge/shape Go test suites, plus the corresponding TypeScript rule-tester suite and config registration.
• Add rule documentation and extend the project dictionary for “promisify” terms.
