Subject: [PATCH 01/11] fix: support Unicode identifiers in Java class name
 validation (#789)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change isJavaIdentifier() regex from ASCII-only /^([a-zA-Z_$][a-zA-Z\d_$]*)$/
to Unicode-aware regex using ES2018 property escapes per JLS §3.8.

This allows non-ASCII identifiers (e.g., Japanese ほげ, Chinese 中文类名,
accented Ñoño) to be accepted in the New Java File and Rename wizards.

Fixes microsoft/vscode-java-dependency#789

Subject: [PATCH 02/11] test: fix flaky simple project name assertion

The .project file defined name '1.helloworld' but JDT LS may override it
with the folder name 'simple'. Align .project name with folder name to
eliminate the inconsistency.

Subject: [PATCH 03/11] test: use name-based lookups instead of hardcoded
 indices

JDT LS may return additional source roots (e.g. target/generated-sources)
that shift node indices. Replace hardcoded array indices with find()-by-name
lookups to make tests resilient to JDT LS version differences.

- Maven: find containers by name instead of [2]/[3]
- Maven: check specific nodes hidden instead of exact count
- Gradle: find nodes by name, increase timeout to 120s
- Multi-module: add assertion guard before getChildren()

Subject: [PATCH 04/11] ci: upgrade GitHub Actions to v4, fix multi-module test
 LS readiness

- Upgrade actions/checkout@v2 -> @v4, actions/setup-java@v1 -> @v4,
  actions/setup-node@v2 -> @v4 across all 3 CI workflows
- setup-java@v4 with distribution: temurin fixes macOS ARM64 JAVA_HOME
- Multi-module test: add languageServerApiManager.ready() to suiteSetup
  so Maven module names are fully resolved before assertions
- Accept folder name or .project name variants for level1 submodule

Subject: [PATCH 05/11] feat: migrate e2e tests from Playwright to autotest
 YAML framework
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the Playwright-based e2e test suite with autotest YAML test plans:

- Add test/e2e-plans/java-dep-project-explorer.yaml
  Covers: focus Java Projects, link/unlink with editor, tree expansion
- Add test/e2e-plans/java-dep-file-operations.yaml
  Covers: create class, create package, rename file, delete file

- Update linuxUI.yml and windowsUI.yml CI workflows to:
  Build VSIX → clone/build autotest → run-all test plans

Subject: [PATCH 06/11] fix: use npm install for autotest, fix rename flow for
 Linux CI

- CI: replace git clone + build with 'npm install -g github:...'
- Fix rename test: use open-file + link-with-editor instead of manual
  tree expansion (avoids tree hierarchy change after package creation)

Subject: [PATCH 10/11] fix: use fillAnyInput for rename (handles both inline
 and quick input)

On Linux, context menu Rename may trigger VSCode's built-in inline
tree rename instead of the extension's showInputBox. fillAnyInput
detects whichever input appears and fills it.
