Migrate build to Maven, modernise Java APIs, upgrade to JUnit 5

Comprehensive Java 25 migration and tech-debt reduction across the full
project. All changes verified via `mvn compile` and `mvn test-compile`
with zero errors.

- Add pom.xml: Maven 3 build replacing Ant; Java 25 compiler release;
  maven-surefire-plugin 3.5.2, exec-maven-plugin 3.4.1,
  build-helper-maven-plugin 3.6.0, maven-jar-plugin 3.4.2
- Add rasterize-milstd2525 Maven profile (antrun + batik-all:1.17)
  replacing the bundled Batik 1.7 JARs
- Update run-demo.bash / run-demo.bat to launch via `mvn exec:exec`

- Add .github/workflows/ci.yml: Temurin 25, `mvn compile` + `xvfb-run
  mvn test`, Surefire report upload on failure
- Add .github/workflows/release.yml: tag-triggered; builds JAR +
  Javadoc zip; publishes via softprops/action-gh-release@v2
- Archive .travis.yml → .travis.yml.archived

- Remove 8 bundled JOGL 2.4-rc / GlueGen JARs (total ~4.4 MB)
- JOGL 2.6.0 and GlueGen 2.6.0 now resolved via Maven Central;
  required --add-opens flags declared in pom.xml surefire/exec config

- Replace OS-specific reflection branches (com.apple.eio.FileManager,
  Runtime.exec) with java.awt.Desktop.browse()

- Replace removed sun.arch.data.model property with os.arch checks
  (x86, i386, i686) for 32-bit architecture detection

- Remove 75 vendored Jackson 1.x source files under src/org/codehaus/
- Add com.fasterxml.jackson.core:jackson-core:2.18.2 Maven dependency
- Migrate 5 WWJ source files: org.codehaus.jackson.* →
  com.fasterxml.jackson.core.*; factory.createJsonParser() →
  factory.createParser(); parser.getCurrentName() → parser.currentName()
- Update LICENSE.jackson.txt to reference FasterXML 2.18.2

- Remove lib-external/batik/ (Batik 1.7+r608262 + Ant 1.6.5, ~7.7 MB)
- SVG→PNG rasterisation now runs via the new rasterize-milstd2525 Maven
  profile at release time (no compile-time dependency)

- Replace junit:junit:4.13.2 with org.junit.jupiter:junit-jupiter:5.11.4
  (aggregator: API + engine + params; Surefire 3.5.2 auto-discovers)
- Migrate all 49 test files:
  · @RunWith(JUnit4.class) removed (47 files)
  · @RunWith(Parameterized.class) → @ParameterizedTest @MethodSource
    (KMLExportTest, ShapeAttributesTest — constructors removed, data()
    returns Stream<List<Exportable>> / Stream<Arguments>)
  · @Before/@after → @BeforeEach/@AfterEach (8 files)
  · @ignore → @disabled (4 files)
  · @test(expected=…) → assertThrows() (KMLExportTest)
  · All org.junit.Assert/org.junit.* imports → org.junit.jupiter.api.*
  · 1,688 assert argument-order fixes (JUnit 4 message-first →
    JUnit 5 message-last) across 35 files
  · Private assertEquals(Iterable<T>…) helpers renamed
    assertIterablesEqual in 3 layer test files to prevent name-shadowing

- Add MIGRATION_JAVA25.md: complete migration guide + tech-debt register
  (TD-01 through TD-11) with priority scores and completion status
