DB & Dev Tools · Databases: connections, schemas, queries, structure, Redis

A new chapter, src/devtools. ConnectionManager lists saved connections
with their engine and address, or why one failed, and connects on Enter;
ConnectionForm fills a connection with a port checked from 1 to 65535,
tests it and saves it. SchemaTree shows schemas, tables, views and
fields with keys marked; ERDiagram draws tables and their foreign keys
on NodeGraph, whose fixed wires show only the sockets that hold one.
QueryHistory finds past runs and runs one again; QueryPlanViewer shows
each step's share of the cost. TableStructureEditor edits fields in
place; IndexManager lists and draws up indexes; RedisKeyBrowser finds
keys by glob and lays out each type. QueryEditor is editor::CodeEditor,
whose lexer now knows SQL's words, and QueryResultGrid is
tables::DataGrid. lists::row_action keeps a row's button its own.

 - A ScrubInput shows its number in about 140px beside a short label. In a narrower column a pair hides it, so a long label takes a row of its own (`canvas::TypographyPanel`).
 - Design panels edit a whole value and hand the owner a changed copy through `canvas::panel::editing`. A swatch that opens a picker is `canvas::panel::color_well`.
 - A press that stops propagation also stops the ancestors' focus on press. A layer that takes keys focuses itself in its own press handler (`canvas::ToolLayer`, `canvas::MindMap`), and a field over it stops its own presses.
+- A button inside a pressable row goes through `lists::row_action`, which keeps its press and its Space or Enter from the row (`devtools::ConnectionManager`).
 - A field opened over a component hands focus back to that component on Enter and Escape, through `forms::Editing`'s `returning` and `give_back` (`canvas::writing`); a blur keeps the words and leaves focus where it went.
 - A focus ring on a box whose children measure themselves goes on an overlay child: a border insets the children and shifts what they measure (`canvas::ToolLayer`).
 - A menu of times goes through `mail::times`: each row names its day and hour, a moment comes once (tomorrow is next Monday on a Sunday), and "Pick a time…" opens one dialog that waits for a time ahead of now (`ScheduleSend`, `SnoozePicker`).
