v0.1.0

Added

• Initial release: MCP server for Wiki.js 2.x, with 62 tools covering pages,
  history, tags, assets, comments, users, groups, system settings and
  maintenance.
• grep_pages, which searches the actual text of pages. Wiki.js' default
  search engine ("Database - Basic") indexes only titles and descriptions, so
  search_pages cannot find anything written inside a page — it now reports
  which engine is active and says so.
• A concurrent-edit guard on update_page. It compares against the moment the
  caller read the page, refuses to overwrite somebody else's save, and can be
  overridden deliberately with force.
• Surgical edits: update_page takes edits with a find-and-replace contract
  that requires each anchor to match exactly once, rather than silently editing
  the first occurrence.
• get_page modes for metadata, an outline, a named section, and a character
  window, so a large page can be read without filling the context.
• diff_page_versions, a unified diff between two stored versions or between a
  version and the live page.
• upload_asset, which Wiki.js 2.x has no GraphQL mutation for.
• WIKIJS_ALLOWED_PATHS, confining the writing tools to page path prefixes,
  matched by path segment.
• WIKIJS_READ_ONLY, WIKIJS_ALLOW_TOOLS / WIKIJS_DENY_TOOLS with an
  essential preset, and confirmation tokens on every destructive or
  administrative operation.
