Migrate interaction tag to JLine 2 API

[skrcode]

Summary

This completes the JLine 2.14.6 upgrade proposed in #104.

JLine 2 moved the console, history, and completion APIs used by AskTag. This migration:

• uses jline.console.ConsoleReader
• preserves the shared in-memory history with MemoryHistory
• rebuilds history-based completions from the JLine 2 History.Entry iterator
• replaces SimpleCompletor with StringsCompleter

The existing prompt, default-answer, predefined-completion, and cross-invocation history behavior is retained.

Verification

• mvn -B --no-transfer-progress -pl jelly-tags/interaction -am clean verify on JDK 8
• the same reactor build on JDK 25
• 133 Commons Jelly core tests passed on each JDK
• interaction module compiled and packaged on both the minimum and current Java runtimes
• Apache RAT, Animal Sniffer, build-plan checks, and SBOM generation completed
• git diff --check
