chore(java): bump version to 0.4.0

[shps951023]

Summary

Bump the Java implementation version from 0.3.0 to 0.4.0 in preparation for the
Maven Central release.

Changes

• minipdf-java/pom.xml: parent version 0.3.0 -> 0.4.0
• minipdf-java/minipdf/pom.xml, minipdf-java/minipdf-cli/pom.xml, minipdf-java/minipdf-tests/pom.xml: parent version 0.3.0 -> 0.4.0
• MiniPdfCommand.java: CLI --version string -> minipdf-java 0.4.0
• minipdf-java/README.md: dependency, CLI artifact, and release-tag examples -> 0.4.0

Validation

• mvn -B -ntp clean verify compiles all modules and produces minipdf-0.4.0.jar and minipdf-cli-0.4.0.jar.
• Tests: 78/79 pass. One pre-existing failure remains:
  ClassicFixtureSmokeTest.preservesVietnameseTextAndPaginationInIssue91
  (Vietnamese text mojibake), unrelated to this version bump.

Note

The Maven Central Publish workflow runs ./mvnw -B -ntp clean verify in its
"Test release candidate" step, so the pre-existing Vietnamese test failure will
block publishing until that test is fixed or otherwise resolved.

Summary by CodeRabbit

• Documentation

  • Updated Maven dependency, CLI download, usage, and release publishing examples to version 0.4.0.

• Release

  • Updated the project and CLI version references to 0.4.0.
  • The CLI now reports version 0.4.0 when using its version option.
