📋 Implement Automated Changelog Generation

[sfloess]

Problem

CHANGELOG.md updates are manual.

Solution

Use conventional commits + automation:

Option 1: git-changelog-maven-plugin

<plugin>
    <groupId>se.bjurr.gitchangelog</groupId>
    <artifactId>git-changelog-maven-plugin</artifactId>
    <configuration>
        <templateFile>changelog.mustache</templateFile>
    </configuration>
</plugin>

Option 2: GitHub Actions

Use conventional-changelog-action

Commit Format

feat: add TLS support to REST API
fix: path traversal vulnerability
docs: update CONTRIBUTING.md
