chore: gitignore Rust target/ build output

[carlos-alm]

Summary

• Adds target/ to .gitignore. Cargo writes workspace build artifacts there (~582MB locally) and the directory was previously untracked, polluting git status and risking accidental commits of build output.

Test plan

• git status no longer shows target/ as untracked after a cargo build
• Existing tracked files unaffected

PR Review Analysis

Reviewing this gitignore change following the codegraph review process:

Todo List:

• Read the changed .gitignore file
• Phase 1: Root cause analysis
• Phase 2: Configuration change detection
• Phase 3: Test integrity check
• Phase 4: Code quality assessment
• Phase 5: Backlog compliance evaluation
• Provide final structured assessment

Root Cause Analysis

Problem Being Solved: Cargo build artifacts (~582MB) in target/ directory were untracked, polluting git status output and creating risk of accidental commits of build output.

Why This Approach: Standard Rust practice - target/ contains generated binaries, incremental compilation artifacts, and dependency builds that should never be version controlled. This is the correct solution, not a workaround.

Risk Assessment: Zero risk - this is purely additive to .gitignore and follows universal Rust conventions.

Backlog Compliance

• Zero-dep: ✓ - no new runtime dependencies, pure gitignore change
• Foundation-aligned: ✓ - infrastructure hygiene, prevents accidental commits of build artifacts
• Problem-fit: 3/5 - useful developer experience improvement but doesn't directly address core "AI navigation" problem
• Breaking: No - gitignore changes are never breaking
• Tier: 1 (zero-dep ✓ + foundation-aligned ✓)

Phase Analysis Results

✅ Phase 1: Real problem, correct solution
✅ Phase 2: No configuration relaxation - purely additive gitignore entry
✅ Phase 3: No test changes, proper test plan provided
✅ Phase 4: Perfect implementation - single line, standard practice
✅ Phase 5: Tier 1, no concerns

Critical Concerns

None. This is textbook infrastructure hygiene.

Final Recommendation

• Rating: ⭐⭐⭐⭐☆ (4/5)
• Action: APPROVE
• Reasoning: Correct, standard solution to a real problem. No complexity, no risk, follows universal Rust conventions. Only reason it's not 5 stars is that it's routine infrastructure maintenance rather than exceptional contribution.

The test plan is appropriate and the change is exactly what any Rust developer would expect.

Greptile Summary

Adds target/ to .gitignore so Cargo's workspace build output (up to ~582 MB) is no longer tracked or surfaced in git status.

• Single-line addition to .gitignore; no existing entries are modified and no tracked files are affected.
• target/ is the conventional Cargo build directory — ignoring it is standard practice for Rust projects.

Confidence Score: 5/5

Safe to merge — adds a single, well-understood gitignore entry with no risk to tracked files or existing workflows.

The change is a one-line .gitignore addition that excludes the standard Cargo build directory. No tracked files are touched, no behaviour changes, and ignoring target/ is the universally accepted practice for Rust workspaces.

No files require special attention.
