Subject: [PATCH] fix: use POSIX-compliant awk bracket expressions for busybox
 compat

[\[\] ] relies on GNU awk treating backslash as an escape inside
bracket expressions. POSIX awk (including busybox) treats backslash
literally, causing the regex to silently fail and suppress all output
from ready, blocked, ls, and other listing commands. Use [][ ] instead,
which is portable across all awk implementations.

 ## [Unreleased]
 
+### Fixed
+- Use POSIX-compliant bracket expressions in awk regexes for busybox compatibility
+
 ### Added
 - Plugin system: executables named `tk-<cmd>` or `ticket-<cmd>` in PATH are invoked automatically
 - `super` command to bypass plugins and run built-in commands directly
