Description

Support Confluence tiny links (/wiki/x/<code>) as pageId input in extractPageId.

When Confluence's "Copy link" or "Share" button is used, it generates a tiny link (e.g., https://example.atlassian.net/wiki/x/aBcDeFg). Previously, this format was not recognized by the CLI. This PR resolves tiny links by following the HTTP 302 redirect to obtain the actual page URL, then extracts the page ID using existing logic.

Closes #100
