#1594: Implement release commandlet

[laert-ll]

This PR fixes #1594

Implemented changes:

• Added ide release commandlet that automates building and deploying a release: derives the release version from .mvn/maven.config (-Drevision=), commits and tags it, runs the Maven deploy build, bumps to the next -SNAPSHOT version, and pushes after confirmation.
• Guards: aborts on uncommitted changes, warns when run on a fork, and requires the top-level project (or --force).
• Build goals are configurable via MVN_RELEASE_OPTS (default clean deploy -Dchangelist= -Pdeploy); failed builds can be retried.
• Added commit, tag, push, and retrieveGitRemotes to GitContext.

Testing instructions

1. In a project using -Drevision= versioning (e.g. IDEasy itself), run ide release from the project root.
2. Confirm it proposes the correct release/next versions, then creates the set release version commit + release/ tag, builds, and creates the set next version commit.
3. Answer no at the final "Do you want to continue?" prompt to abort before pushing — verify nothing is pushed. To clean up: git reset --hard HEAD~2 && git tag -d release/.

@laert-ll thank you for your PR. Great work 👍
Since this was somehow stuck in team-review without a reviewer assigned and I came across, I took the fast lane and moved it to the final review.
Regarding my reivew comments you did nothing wrong. I just want to improve the design for better SoC, reuse and maintainability.
