The #2595 job-queue rework replaced hive-bash-mcp's direct broker send
with a todo push through the in-agent socket, so a bash-task-driven
turn now wakes with from == "todo", never "bash-task-<id>". This
branch has had nothing to match since, so it silently bucketed no
turns under the bash-task label; removed rather than left dead.
Closes#2256.
Closes the #3110 split — lib.rs is now just the crate doc comment and
the pub mod list.
journal.rs's new doc comment fixes a pre-existing bug: the old
JournalPriority doc text in lib.rs was actually half Capability's doc
(a leftover from an earlier reorder that moved the code but not the
comment above it).
