0.0.1-internal-api

A build of the internal-api-logpoints branch, for trying log points with the platform's own
inter-line machinery back in place. Not for Marketplace, and not a release of the plugin —
everything that makes this different from main is @ApiStatus.Internal.

Install: Settings | Plugins | ⚙ | Install Plugin from Disk…, pick the zip below, restart.

What to look at

• The yellow dot sits in the gap, level with its own Log: box, instead of a line below it —
  in PyCharm and in IntelliJ IDEA.
• Hover between two line numbers in a .by file: the gutter opens a gap with an Add Log icon
  in it. Click to put a log point there. (PyCharm only — IDEA's own provider owns that gap. Needs
  Breakpoints Over Line Numbers, which is the gutter right-click menu under Appearance.)
• Every log point is created between the lines, which is where it runs: after the line above,
  before the line below.
• In IDEA, Ctrl+Alt+F8 (Add Logpoint) now works on .by files at all.

Everything from main still holds: one caret, a yellow Log: caption when the box has focus,
rounded corners, an inlay on a log point added from the gutter menu, and Ctrl+Z taking one back.

Why it cannot ship

supportsInterLinePlacement, the placement enum and getter, the placement-filtered
findBreakpointsAtLine, and the whole InterLineBreakpointConfigurationProvider family are
internal. Marketplace declined this plugin's first submission over internal API and warns that
working around the check risks a permanent ban. docs/internal-api.md on the branch has the full
list, and the IJPL request is for supportsInterLinePlacement and
XLineBreakpointVerticalPlacement to be made public.
