fix: bump native engine version to 3.0.0

[carlos-alm]

Summary

• Bumps crates/codegraph-core/Cargo.toml version from 2.6.0 to 3.0.0 to match package.json
• Fixes codegraph info reporting stale native version and potential unnecessary full rebuilds from version mismatch detection in buildGraph()

Closes #305

Test plan

• After native binary rebuild, verify codegraph info shows Native version: 3.0.0
• Verify no version mismatch warning in codegraph build output

PR Review: Native Engine Version Bump

Reviewing this pull request following strict code review guidelines:

Todo List

• Phase 1: Root cause analysis - understand version mismatch problem
• Phase 2: Configuration change detection - assess risk level
• Phase 3: Test integrity verification
• Phase 4: Code quality review
• Provide structured rating and final recommendation

Root Cause Analysis

Problem Being Solved: The Rust native engine's Cargo.toml version (2.6.0) is out of sync with the main package.json version (3.0.0). This causes:

1. codegraph info to display incorrect "Native version: 2.6.0"
2. Version mismatch warnings in build output
3. Potential unnecessary full rebuilds due to version detection logic in buildGraph() (builder.js:167-175)

Why This Approach: Direct version synchronization is the correct fix. The builder.js code specifically checks prevVersion !== CODEGRAPH_VERSION and triggers full rebuilds when versions don't match. This is functional behavior, not cosmetic.

Risk Assessment: LOW RISK - This is a legitimate bug fix with minimal scope.

Critical Concerns

✅ NO CRITICAL ISSUES FOUND

• ✅ Not a configuration workaround or symptom masking
• ✅ No rules relaxed or tests weakened
• ✅ Single-line version alignment with clear justification
• ✅ Proper test plan provided
• ✅ Addresses documented issue bug: native engine reports version 2.6.0 in codegraph v3.0.0 #305

Code Quality Assessment

• Change Scope: Minimal and targeted - single line version bump from 2.6.0 to 3.0.0
• Version Alignment: Correctly matches main package.json version (line 3)
• Functional Impact: Fixes codegraph info output and eliminates false-positive version mismatch rebuilds
• Test Strategy: Appropriate - verifies both codegraph info output and absence of mismatch warnings

Test Plan Evaluation

The proposed test plan is adequate:

• ✅ Verifies codegraph info shows correct "Native version: 3.0.0"
• ✅ Confirms no version mismatch warning in build output
• ⚠️ Minor Gap: Could benefit from automated test coverage, but manual verification is sufficient for this simple change

Final Recommendation

• Rating: ⭐⭐⭐⭐☆ (4/5)
• Action: APPROVE
• Reasoning: Straightforward bug fix with clear justification, minimal risk, and appropriate testing approach. The change directly addresses a functional issue in the codebase's dual-engine architecture.

Recommendation: Approve and merge. This is a well-scoped fix that resolves legitimate version reporting and rebuild detection issues.
