## What kind of change does this PR introduce?
UI refinements for Explorer query surfaces.
## What is the current behavior?
- The assistant chat textarea uses a tighter radius than the Run SQL /
Create a notebook cards on Explorer home.
- Chart results sit unevenly in the results pane because axis gutters
stack on card padding, and long Y labels can clip.
- Selecting SQL in the editor changes the primary Run button to Run
selected, which is easy to trigger by accident.
- The Prettify SQL icon in notebook query cells uses Lucide's default
size, so it doesn't match other toolbar actions.
## What is the new behavior?
- Assistant chat form uses `rounded-lg` so it matches the home action
cards everywhere the form is used.
- Query result charts collapse unused axis space, add a little padding
when labels are on, and size the Y axis from formatted ticks so longer
labels fit.
- Run is a default split button that always executes the full query. Run
selected is a secondary menu item, disabled until SQL is selected.
- Notebook cell Prettify SQL icons use `size={16}` and `strokeWidth={2}`
like the rest of the Explorer toolbar.
## Additional context
Cmd+Enter in the editor still runs the current selection when there is
one.
## Test plan
- [ ] Open Explorer home and confirm the assistant chat radius matches
the Run SQL and Create a notebook cards.
- [ ] Run a query, switch to chart view, and check spacing with labels
off and on, including large Y values.
- [ ] With no selection, click Run and confirm the full query runs. Open
the split menu and confirm Run selected is disabled.
- [ ] Select SQL, click Run, and confirm the full query still runs. Use
Run selected from the menu to run only the selection.
- [ ] In a notebook query cell, confirm Prettify SQL matches the size
and stroke of nearby toolbar icons.
