TL;DR

Polishes the README so first-time OSS users can immediately see project health, license, contribution, support, and security paths near the top of the repository page.

변경 지점 다이어그램

README.md
├─ top badges: CI, npm, Node.js 24+, MIT, PRs welcome, Code of Conduct
├─ intro note: OSS contribution, support bundle, security reporting guidance
└─ Community and security: clearer links to contributing, security, conduct, license

여기부터 보세요

• README.md top section for badges and the contributor/support note.
• README.md Community and security section for the preserved and lightly improved community links.

위험 & 롤백

• Risk is low: documentation-only change with no runtime behavior impact.
• Rollback is a single README revert if wording or badge selection needs to change.

변경 파일

• README.md — add OSS-facing badges and early contributor/support guidance, then clarify bottom community links.

Evidence

• pnpm install --frozen-lockfile — installed dependencies from the existing lockfile after initial lint showed missing node_modules.
• pnpm lint — pass.
• pnpm test — pass.
• pnpm typecheck — pass.
• pnpm build — pass.
• pnpm exec prettier --check README.md — pass.
• npm view @gh-symphony/cli version --silent — package resolves as 0.4.7.
• gh api repos/hojinzs/github-symphony/actions/workflows/ci.yml --jq '.name + " " + .state' — CI active.
• Direct checks confirmed local links exist for CONTRIBUTING.md, SECURITY.md, CODE_OF_CONDUCT.md, LICENSE, and .github/workflows/ci.yml.
• Direct curl -L --fail checks passed for all added shields.io badge URLs.
• Note: full-repo pnpm format still fails on pre-existing formatting drift in unrelated files; README.md itself passes Prettier.
