test(keys): a shortcut is a chosen subset, not a requirement, item 132

everyActionHasAShortcut() was written when the action list was short and
every action plausibly deserved a chord. Item 123 adds six more, and under
that rule each one consumes a key sequence whether or not anyone would ever
press it. Rarely-used actions were being given chords to satisfy a test
rather than because a user wanted them.

everyActionIsReachableFromAMenu() is the rule that actually matters, and it
already has the right shape: it is what stops an action shipping invisible,
which is the defect item 103 found when `restore` was reachable by a chord
and by nothing a user could see. Discoverability comes from the menu. A
shortcut is an accelerator for the things done often.

Nothing replaces the deleted test and nothing else needed changing:
showShortcutReference() already prints `(unbound)` for an empty sequence, so
the code anticipated this and only the test forbade it.

Verified rather than assumed: with `tag_rules` unbound in defaultBindings(),
an action that is registered, menu-reachable and carries an icon but has no
chord at all, the full suite passes. Before this commit it failed.

CLAUDE.md's "adding an action is FIVE places" paragraph is updated, including
its count of how many are test-enforced, which drops from four to three.

An indeterminate `QProgressBar` beside a status label, built inline in `MainWindow` as `m_syncProgress`, and item 123's composer needs the same pairing. Extract a widget class and convert `MainWindow` to it. It must expose BOTH modes, not just the indeterminate one `MainWindow` happens to need: item 123's send popup drains a determinate bar during its undo countdown and switches the same widget to indeterminate when the command starts. **Not blocked on 123**, and better done first: if 123 lands first it creates the class itself and this row closes with it. The user's position is general, build once and reuse, so the inline habit `CLAUDE.md` records is a description of the code rather than a rule to follow |

Only the BAR was extracted, not the status label this row paired with it. `m_statusLabel` has 34 uses across `MainWindow` for transient messages, selection counts and sync phases, so it belongs to the window rather than to the indicator, and the send popup owns its own phase text |
