v1.14.0

Changed

• Bundled pi upgraded 0.79.4 → 0.83.0 (#85 by @m00kfu). Modern third-party extensions that import newer pi-ai paths (e.g. pi-ai/…/compat) now resolve instead of failing to load. Our runtime patch was re-based onto pi 0.83 and the full test suite re-verified against it.

Fixed

• /dev/null redirects are no longer blocked (#87 by @manueloverride). The shell-write guard counted 2>/dev/null as a destructive file write; it now exempts the null-ish character devices (/dev/null, /dev/stdout, /dev/stderr, /dev/tty, /dev/zero, /dev/random, /dev/fd/N). A redirect to a real file alongside them is still caught.
• A backend that rejects the thinking level no longer loops on "empty response" (#86 by @aole). A provider 400 (e.g. an ollama model that doesn't support thinking) is now treated as an error turn, not an empty model response, so it isn't re-sent three times over pi's real error — which is shown, with a one-line hint to lower the thinking level.
