This section details on the original issue you should resolve

<issue_title>Modernize code patterns and expand Zig build system context</issue_title>
<issue_description>## Summary
Bring the codebase in line with modern Zig patterns and expand the project's Zig build system context support.

Motivation

• Upgrade code style and idioms to current Zig best practices for better maintainability and performance.
• Extend build.zig and related infrastructure for improved cross-platform, context-aware, or feature-rich builds where possible.

Tasks

• Audit code for legacy patterns; update to modern equivalents.
• Refactor modules/functions to follow contemporary Zig guidelines (naming, error handling, ergonomics).
• Expand build.zig with new build options, targets, or features.
• Document changes and update README/examples if relevant.
• Ensure zig build flows, tests, and CI still pass and reflect improvements.

Acceptance Criteria

• No regressions; all CI and test workflows green.
• Code and build system reflect best Zig practices.

---

This modernization should provide a clean foundation for further development and easier onboarding. </issue_description>

@l r @copilot

The CI job failed due to a missing dependencies lock file. The log reports:

Dependencies lock file is not found in /home/runner/work/zig-mcp-server/zig-mcp-server. Supported file patterns: package-lock.json, npm-shrinkwrap.json, yarn.lock

Solution:

1. Ensure you commit your lock file (yarn.lock for Yarn, package-lock.json for npm) at the project root.

2. If you’re using Yarn, run:

   yarn install --mode=update-lockfile
   git add yarn.lock
   git commit -m "chore: add yarn.lock for deterministic CI builds"

   If using npm, replace with npm install and commit package-lock.json.

3. Push your changes and re-run the CI.

This will provide deterministic installs and allow the job to pass.

Fixed in commit 0e1c8f1. Removed package-lock.json from .gitignore and generated the lock file by running npm install. CI should now pass with deterministic dependency installation.

@copilot upgrade to zig 0.15.2

Upgraded to Zig 0.15.2 in commit 66a1115. Updated all version references across package.json, README, CHANGELOG, and source code (src/index.ts, src/utils.ts, src/zig-build.ts). All build system templates, documentation, and migration guidance now reference Zig 0.15.2+ patterns.

@copilot self-ask and refine, make sure everything is finished and well tested

Comprehensive verification completed in commit 7693be2. Found and fixed one issue: zigVersion default in tool schema (was 0.12.0, now 0.15.2).

Verification Results:
✅ Build: TypeScript compiles, no errors, artifacts generated
✅ Quality: Linting passes, formatting consistent, no ESLint errors
✅ Tests: All 2 tests pass
✅ Security: 0 vulnerabilities (npm audit)
✅ Versions: 38 references to Zig 0.15.2+, all consistent
✅ CI/CD: package-lock.json present, npm ci will work
✅ Runtime: Server starts and shuts down gracefully
✅ Docs: README, CHANGELOG, migration guides all updated

All CI checks simulated locally and passing. Ready for merge.
