Bug fixes: - Fix box() calls: set color-pair before box, pass ACS default chtype integers - Fix markdown functions: move to passepartout.channel-tui package where Croatoan is imported; use add-attributes/remove-attributes instead of :bold/:underline kwargs to add-string; call theme-color in gate-trace-lines to convert theme keys to Croatoan colors - Fix sandbox: remove dex:get/dex:post from restricted symbols (blocked neuro-provider from loading) - Export *log-lock* from passepartout (was unbound in jailed skill packages) - Fix configure: always deploy to XDG, skip cp when source==dest - Fix bash crash handler format string (~~ escaping) - Revert test reorder in 28 files (caused package leakage in skill loader) Design cleanup: - Extract tui-run-screen from tui-main for clean separation - Remove inject-stimulus alias - Merge *backend-registry* into *probabilistic-backends* - Fix read-framed-message whitespace DoS (4096-iteration max) - Add *read-eval* nil to dispatcher-approvals-process read-from-string
