Java @XxlJob(CONSTANT) annotations are not extracted into scheduler-facts

[LvYiguang]

Area

gitnexus (CLI / core / indexing / MCP server)

Summary

GitNexus misses XXL-JOB handlers when the @xxljob annotation value is provided via a class constant instead of a string literal.

String literal annotations are extracted correctly:
@xxljob("finConfigProductSync")
public ReturnT finConfigProductSync(String param) {
...
}

But constant-based annotations are omitted:
private static final String JOB_NAME = "TradeStructureTemplateSync";

@xxljob(JOB_NAME)
public ReturnT tradeStructureTemplateSync(String param) {
...
}

Context

scheduler-facts.json contains 16 xxlJobs, while source scan finds 17 @xxljob annotations.

The missing job is:
TradeStructureTemplateSync

Expected behavior

GitNexus should resolve same-class static final String constants used as annotation values and include the job:
tradeStructureTemplateSync

Actual behavior

The missing job is:
TradeStructureTemplateSync

Steps to reproduce

package demo;

import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.annotation.XxlJob;

public class DemoJob {
private static final String JOB_NAME = "demoJob";

@XxlJob(JOB_NAME)
public ReturnT<String> run(String param) {
    return ReturnT.SUCCESS;
}

}

Run GitNexus analyze/facts generation and inspect scheduler-facts.json.

Likely Cause
The scheduler facts extractor appears to handle annotation string literals, but not identifier references that resolve to private static final String constants in the same class.

Acceptance Criteria

@xxljob("demoJob") is still extracted.
@xxljob(JOB_NAME) is extracted when JOB_NAME is a same-class static final String.
The extracted job name should be the constant value, not the identifier name.
Existing scheduler facts output shape remains unchanged.

Environment

gitnexus 1.6.5

I’d like to take this as a separate focused PR after #2037. Scope will be conservative same-class static final String resolution for @xxljob annotation values, preserving literal behavior and scheduler-facts output shape, with positive and unresolved-identifier negative fixtures.

I traced this against current main (3b195ec), all fetched upstream/origin refs, and GitHub code search. The repository currently contains no scheduler-facts/scheduler-facts.json generator and no XxlJob/xxlJobs extraction path, so there is no existing output contract or test surface to extend conservatively. Could you point me to the extractor/path that produces the 16-entry scheduler-facts.json, or confirm whether that generator lives outside GitNexus? Once clarified, I can implement same-class static final String resolution with literal, positive constant, and unresolved-identifier negative regressions.
