hive-sh4re: lift TaskFile + TaskStatus from hive-bash-mcp

Move the bash-task on-disk schema (TaskFile + TaskStatus) into hive-sh4re,
the shared wire-types crate, and re-export them from hive-bash-mcp::protocol
so existing in-crate imports keep compiling. This gives hive-ag3nt's agent
web UI a canonical type to deserialize when reading the bash-tasks dir for a
running-tasks panel, instead of a parallel struct that would silently drift
from the daemon's persisted format. Both crates already depend on hive-sh4re,
so no new dependency edges.
