Modernize build: Java 21, Tika 3, PDFBox 3, JUnit 5.
Bump all dependencies and plugins to current versions. Replace the
tika-parsers bundle with a direct PDFBox dependency (we need
PDFTextStripper control), add java-diff-utils for the synopsis diff,
and add JUnit 5 with AssertJ for testing. Drop unused dependencies
(tess4j, Lanterna, term4j, sqlite-jdbc, imageio codecs, annotation
libraries) in favour of jspecify. Regenerate the Maven wrapper with
the official plugin (Takari is dead) and remove the vestigial Ant
wrapper and Tika configuration.
