Chore: Centralize generated content

[kduy969]

Introduces config.json at the repo root as the SSOT for internal path constants (.bazel-jdt/, .bazelproject, projects/, aspects/), replacing all hardcoded strings across the stack:

• Rust: internal_config module reads via include_str! at compile time
• Java: Maven copies root config.json into the JAR at build time; InternalConfig loads it from classpath
• TypeScript: esbuild inlines the JSON import at bundle time

Generated files location changes:

• .bazelproject → .bazel-jdt/.bazelproject
• .bazel-projects/ → .bazel-jdt/projects/
• .bazel-jdt/aspects/ — unchanged, already in place

Also create .gitignore inside .bazel-jdt folder to ensure all generated files are ignored

is_bazelproject_file should check both the name and the location

Hi, @kduy969 It is recommended that when generating the .bazel-jdt directory, the .gitignore file is generated in the directory by default and ignores all file contents in this directory.

After loading examples/simple-java-project, Java Unit Explorer did not find any targets. Below is my .bazeproject file configuration.

# Generated by Bazel JDT Bridge
directories:
  app
  greeter
  tests

derive_targets_from_directories:
  True

test_sources:
  tests/**

bazel_binary: bazelisk

java_language_level: 21

ok, let me put this behavior back

I got the same issue as @kduy969, the Unit Test Codelens and Test explorer disappeared:

How about we continue use folder .eclipse as the Centralize generated folder?

@zhirui1994 Actually, I didn't want to share a directory with previous plugins, which necessitated adding logic to clear the previous directory.

Got it, makes sense.

@kduy969 I think the logic for ensureProjectGitignore should be modified to create a .gitignore file in the .bazel-jdt directory with the following content: *
