docs: add contributing guide and community files #166

[mart-sessman]

Closes #166

Part of TEDI-Design-System/general#247.

• CONTRIBUTING.md: reporting issues (bugs, Discussions, design repo, security), making a change, the direct release from rc, local setup, and the Figma token sync (which files are generated, how the sync PR works, running the export locally).
• .github/ISSUE_TEMPLATE/config.yml: contact links for private security reports, Slack, Discussions and the design repo. Blank issues stay enabled.
• README.md: Contributing section points to CONTRIBUTING.md and fixes the wiki link. The README is copied into the npm package.

PRs use the organization default template from TEDI-Design-System/.github#1, which also adds the code of conduct, security policy and support page this guide links to, so the two should be merged together.

Summary by CodeRabbit

• Documentation
  • Added guidance on where to report security concerns, usage questions, proposals, design issues, and other repository issues.

📝 Walkthrough

The pull request adds issue-reporting contact links and contributor guidance. The guide documents the change workflow, local development setup, and maintenance of Figma-generated design tokens. The README points contributors to the guide and wiki.

Changes: Contribution and Repository Guidance

Layer / File(s)	Summary
Issue reporting routes .github/ISSUE_TEMPLATE/config.yml, CONTRIBUTING.md, README.md	The issue template provides contact links for security reports, usage questions, proposals, and design or UX problems. CONTRIBUTING.md adds reporting guidance, and the README links to that guide and the wiki.
Contribution workflow and local setup CONTRIBUTING.md	The guide documents the branch and commit conventions, pull-request target, release behavior, React and Angular checks, Node.js requirement, and local install, lint, and build commands.
Design-token maintenance CONTRIBUTING.md	The guide identifies Figma-generated token files and documents the sync process, how to request token corrections, local export requirements, and manually maintained variable files.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to d04dc

The guide’s community links may not work until the companion PR lands, and automatic code-owner review routing is absent. Confirm the links and add or explicitly defer CODEOWNERS before merging.

• observed — CONTRIBUTING.md (service) was modified; 1 changed file maps to changed impact.
• observed — README.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in CONTRIBUTING.md: Adds repository contribution guidance, including where to report bugs, feature ideas, design issues, security vulnerabilities, and questions.
• observed — Modified behavior in CONTRIBUTING.md: Adds the change workflow: open an issue, branch from rc using the prescribed naming pattern, follow the commit convention, and target pull requests to rc. States that merges to rc publish a package version and changes should be checked against React and Angular.
• observed — Modified behavior in CONTRIBUTING.md: Documents Node.js 24 as the requirement, lists install, lint, and build commands, and describes using the local dist/ build to try changes in React or Angular.
• observed — Modified behavior in CONTRIBUTING.md: Documents that listed token files are generated from Figma and should not be edited manually; describes the weekday/on-demand sync workflow, token-change reporting, local export requirements, and that other variable files are maintained by hand.

Explanation

Issue #166 requires a contributing guide for tokens, Figma variable sync, and the wiki. CONTRIBUTING.md provides this guidance. .github/ISSUE_TEMPLATE/config.yml provides Slack and Discussions contact links and keeps blank issues enabled. The repository file list at the reviewed head contains no pull request template with a Definition of Done and no CODEOWNERS file. The PR description's reference to the organization repository does not establish that these requirements are present in this pull request.

Review comments at @CONTRIBUTING.md:
- Line 5: Update the links in CONTRIBUTING.md to point to destinations that
already exist, or ensure the referenced Code of Conduct, security policy, and
support files are available before publishing the links.
- Line 20: Add a CODEOWNERS file in a GitHub-supported location with the agreed
owner assignments so GitHub can request code-owner reviews; if the requirement
is deferred, explicitly record that decision instead.
- Line 22: Update the Core release description to say that merges with
release-triggering commits publish a new package version, rather than implying
every merge does; leave the React and Angular compatibility guidance unchanged.
