fix: infinite loop in pos completion walk-up caused CPU hang on TAB

Browse Source 
_pos_complete_tool walks up the key looking for a tool that declares
POS_FLAGS/POS_SUBCMDS; "${k%-*}" on a dash-free key returns it
unchanged, so once the walk hit a bare category (e.g. 'system' from
system-nfs-server) the while loop spun at 100% CPU. Any TAB at an
argument position of a tool without flags/subcmds froze the shell.
Stop the walk-up when no dash remains.

Also refresh AGENTS.md quick facts and regenerate doc file table
(completions/pos.bash 278->279 lines).
