Improve Spring AI version consistency validation

[codingkiddo]

Summary

Improve scripts/check-spring-ai-version.sh so that Spring AI version validation is more portable and accurate.

The previous implementation used a Bash associative array through declare -A, which is unsupported by the default Bash version available on macOS.

The checker also considered Spring AI version declarations contained inside XML comments, which could cause false version inconsistencies.

Changes

• Remove the Bash 4-only associative array usage.
• Support execution with the default macOS Bash.
• Detect Spring AI versions declared through <spring-ai.version>.
• Detect versions declared directly on the spring-ai-bom dependency.
• Ignore Spring AI declarations contained inside XML comments.
• Report an error when no active Spring AI version declarations are found.
• Return a non-zero exit code when multiple active versions are found.
• Add a regression test covering an active version alongside a commented-out version.

Example

The following commented declaration is now ignored:

<!-- <spring-ai.version>1.1.3-SNAPSHOT</spring-ai.version> -->
<spring-ai.version>2.0.0-SNAPSHOT</spring-ai.version>

Previously, both versions could be reported, resulting in a false inconsistency.

Testing

bash -n scripts/check-spring-ai-version.sh
bash -n scripts/tests/check-spring-ai-version-tests.sh

./scripts/tests/check-spring-ai-version-tests.sh
./scripts/check-spring-ai-version.sh

Repository result:

2.0.0-SNAPSHOT: 77 files
All detected declarations use Spring AI version 2.0.0-SNAPSHOT
