Add Confluence Cloud support alongside Data Center

- CloudConfluenceClient: v2 API for page get/update; inherited v1 endpoint
  for attachment upload (v2 has none). Auto-detected from *.atlassian.net
  hostnames; instance_type config field overrides for custom domains.
- Cloud auth: CONFLUENCE_EMAIL + CONFLUENCE_TOKEN (API token) basic auth,
  not gated behind --unsafe-auth. /wiki is appended to bare site URLs and
  written back to config so attachment URL matching keeps working.
- Attachment content reads use the REST download endpoint on Cloud; the
  legacy /download/attachments path 401s for API-token auth there.
- Credentials may come from the environment without a .csync.env file;
  csync injects FIFO-served env files (e.g. 1Password) via --env-file
  since Docker VM file sharing cannot pass host FIFOs.
- Portable BSD/GNU sed in the release Makefile.
- README/CLAUDE.md/examples updated; note on IPv6-related image build
  failures and the Docker Desktop IPv4-only fix.

 ## Confluence API reference
 
+Data Center (v1, base `{confluence_url}/rest/api`):
+
 - Get page: `GET /rest/api/content/{id}?expand=body.storage,version,title`
 - Update page: `PUT /rest/api/content/{id}` with JSON body (see `update_page()`)
 - Upload attachment: `POST /rest/api/content/{id}/child/attachment`
 - Space content: `GET /rest/api/space/{KEY}/content`
 
-All endpoints are Confluence DC REST API v1 (`/rest/api/`). This tool does not use the
-v2 API (`/api/v2/`) introduced in newer DC versions.
+Cloud (base `{confluence_url}` = `https://site.atlassian.net/wiki`):
+
+- Get page: `GET /api/v2/pages/{id}?body-format=storage` — response carries `title`,
+  `version.number`, and `body.storage.value` in the same shapes the v1 consumer code
+  reads, so `cmd_pull`/`cmd_push` are client-agnostic.
+- Update page: `PUT /api/v2/pages/{id}` with `{id, status: "current", title, body, version}`
+- Upload attachment: `POST /rest/api/content/{id}/child/attachment` — still v1; the v2
+  API has no attachment upload endpoint.
+- Download attachment content: `GET /rest/api/content/{id}/child/attachment/{attId}/download`
+  (redirects to a signed media URL). The legacy `/download/attachments/{id}/{file}` path
+  returns 401 for API-token auth on Cloud — it only accepts browser-session cookies —
+  which is why `download_attachment_text()` is overridden in the Cloud client.
+
+Atlassian is deprecating Cloud v1 content endpoints on a rolling timeline, which is why
+Cloud page reads/writes use v2 while DC stays on v1.
