Community governance rollout for eAI

This issue tracks the isolated community-governance rollout for embeddedos-org/eAI.

Scope (from master @ abd678b6c627f8e960657d03fa6309d1448c7c37)

1. Reconcile AGENTS.md — concise, truthful, repo-specific: exact build/test commands from README.md/CONTRIBUTING.md, contribution/security pointers. No invented lint/format commands.
2. Copy the six wiki sources byte-for-byte into docs/wiki/ (Home.md, Getting-Started.md, Development.md, Security.md, FAQ.md, _Sidebar.md).
3. Add .github/workflows/linked-issue.yml calling embeddedos-org/.github/.github/workflows/linked-issue-policy.yml@92cb596c773496ec4df76717e8acf0e6b7700f73 with policy_ref: 92cb596c773496ec4df76717e8acf0e6b7700f73 (both tokens replaced, no placeholder left).
4. Reconcile .github/PULL_REQUEST_TEMPLATE.md — preserve every repo-specific section, add exactly one top-level Closing issue section with canonical guidance and Fixes #<same-repository issue number>.

Acceptance criteria

• AGENTS.md is concise/truthful with exact build/test commands and contribution/security guidance.
• Six docs/wiki/*.md files are byte-identical to the wiki sources.
• .github/workflows/linked-issue.yml parses as YAML, uses the exact caller path, pins the exact SHA twice, and contains no POLICY_COMMIT_SHA placeholder.
• .github/PULL_REQUEST_TEMPLATE.md preserves all repo-specific sections and has exactly one top-level Closing issue section with canonical guidance and Fixes #<same-repository issue number>.
• Markdown local links resolve; documented commands recorded; diff is limited to the intended files.
• Exactly one commit on a normal feature branch, pushed with a normal (non-force) push; one draft PR with Fixes #N.
• No merge/close/force/default-branch writes/settings changes.
