feat: generate the gt command reference from gitea/cli

update_cli_docs.sh runs gt's own generator and lays the pages out for the
site: one directory per command group, front matter, titles, sidebar
order, fenced help text and rewritten links. --released succeeds while no
series is documented. A weekly workflow proposes updates like the runner's.

+
+JSON output with --json and --jq
+
+## Synopsis
+
+```text
+gt prints text for people by default. Scripts should use JSON: the columns and
+wording of text output may change between releases.
+
+  --json             print every field
+  --json FIELDS      print only the comma-separated FIELDS, such as --json number,title
+  -q, --jq EXPR      filter the JSON with a jq expression; implies --json
+
+The JSON FIELDS section of a command's help lists its fields, and shell completion
+offers them after --json. An unknown field reports the available ones.
+
+--jq runs inside gt, so jq does not need to be installed. String results print
+without quotes:
+
+  $ gt issue list --json number,title --jq '.[] | "\(.number)\t\(.title)"'
+
+Some fields cost extra requests, such as the reviewers of pr list, the blocked_by and blocks
+of issue view and issue edit, and the visibility of org member list. gt makes them only when
+the output includes the field: --json names it, or --json selects every field and the --jq
+expression names it. An expression that reaches such a field without naming it, as
+to_entries does, sees it empty; name the field in --json instead.
+
+On a terminal, JSON is indented and colored; otherwise each value prints on one line.
+Commands that return no resource, such as deletes, reject --json.
