- Add "Runtime environment" section to codeact_preamble.md documenting
Monty's restrictions: no stdlib imports, single imports only, no classes/
with/match/del/yield, available builtins and modules, workarounds
- Add MONTY.md tracking current pin, all limitations, upgrade process,
and changelog for future Monty updates
- Fix gateway createNewThread() not resetting read-only state — new
threads now eagerly enable chat input instead of waiting for async
loadThreads() callback
