codeberg_api is a bash function in the gardener script's own process,
not available to claude-p's tool execution environment. Claude was
silently failing to call it and returning CLEAN.
Switch to curl commands with $CODEBERG_TOKEN env var that claude-p
can actually execute via its bash tool.
Tech-debt→backlog promotion was only in prompt text, not in the
problem list. Claude focused on detected problems (dupes, thin issues)
and printed CLEAN, ignoring the primary mission.
Fix: explicitly list up to 10 tech-debt issues in the problem list
so claude sees them as actionable items.
Also bumped --max-turns from 10 to 30 — promoting issues requires
reading + editing + relabeling via API, needs more turns.
