fix(docs): #2 wiki/Home.md — landing page for GitHub Wiki mirror

[hanwencheng]

Summary

Adds wiki/Home.md — the landing page for the GitHub Wiki — and documents the companion CI workflow that must be added manually (the OAuth token used for this PR cannot push .github/workflows/*).

What changed

• wiki/Home.md — landing page with an "edit the source, not the web UI" banner + index of the 6 existing wiki pages.

What a maintainer must add manually

The CI workflow file .github/workflows/publish-wiki.yml could not be pushed from this session (OAuth token lacks the workflow scope — a standard GitHub restriction for safety). A maintainer should add this file in a follow-up commit (via the GitHub web editor, or locally with a PAT that has the workflow scope):

name: Publish wiki

# One-way mirror: wiki/ in this repo is the canonical source for the GitHub Wiki.
# Every push to main that touches wiki/ copies the folder over to
# litentry/agentKeys.wiki.git.
#
# Edits made directly through the GitHub Wiki web UI will be overwritten on the
# next push to main that touches wiki/. See wiki/Home.md for the developer note.

on:
  push:
    branches: [main]
    paths:
      - 'wiki/**'
  workflow_dispatch:

jobs:
  publish:
    runs-on: ubuntu-latest
    concurrency:
      group: wiki-publish
      cancel-in-progress: false
    permissions:
      contents: write
    steps:
      - name: Checkout main repo
        uses: actions/checkout@v4

      - name: Publish to wiki
        uses: Andrew-Chen-Wang/github-wiki-action@v4
        with:
          path: wiki/

Prerequisite (manual)

GitHub doesn't create litentry/agentKeys.wiki.git until at least one wiki page has been saved through the web UI. Before the workflow can run:

1. Visit https://github.com/litentry/agentKeys/wiki, click "Create the first page", save anything.
2. Merge the workflow file (above).
3. The next push that touches wiki/** will trigger the mirror.

Test plan

• wiki/Home.md renders cleanly in a markdown preview.
• After workflow is merged and the wiki repo is initialized: push a trivial wiki/ change and confirm the action runs.
• Confirm paths: ['wiki/**'] filter means non-wiki commits don't trigger the workflow.

Issue

Closes #2 (documentation + initial Home.md). Workflow file tracked as "add by maintainer" in the PR body.

Verdict

PR merged before review ran. HEAD of fix/issue-2 is an ancestor of origin/main (PR #26 already landed on main via merge commit 17213b7). codex review --base main correctly reported no patch to analyze. No actionable findings.
