Studio 3.1.1: four corrections, three of them to what 3.1.0 broke

[dmitrat]

Found the day 3.1.0 shipped, by using it. Engine 14.0.0, unchanged - nothing on NuGet moves.

What is corrected

The double click opens a table's data again	It had done nothing at all since the repair meant to fix it: DoubleTapped travels Bubble alone, and a handler asked for its tunnelling route is no handler (#222).
…and no longer opens the row as well	Handling the press does not stop the tap, so the tree still toggled itself.
A double click on the connection opens its Database tab	The same rule rather than a fourth exception: a double click opens the thing the node IS (#223).
No rule with nothing beside it	All fourteen kinds of node drew separators belonging to items that hide themselves (#221).
The status line takes back what is no longer true	Editing table: Products with no editor open (#224).

Known issues - the part worth reading

Two engine defects were found in the same pass and are deliberately not fixed here, because the engine did not move. Both are written up with their reproduction and root cause in Docs/KnownIssues.md:

• 25. A join condition written the other way round is refused. ON right.x = left.y fails with Column 'x' not found; in a chain, "the left input" is everything joined so far. Root cause named to the line - OptimizerJoinCondition.TryExtractEquiJoinKey pairs the keys by written order and never asks which input each column belongs to. Measured table of what works and what does not, plus the workaround.
• 26. EXPLAIN gives the right input's child the wrong parent. Anything drawing the plan as a tree draws the wrong tree faithfully - the renderer is not the defect.
• 27. A gap in Studio: a routine in the tree can only be refreshed, though the engine has DROP FUNCTION and the catalogue already carries the body.

Studio: 1030 green.
