Levi Neuwirth 90fc7a913e fix(window): wire the side-window split guard and scope the divider drag
PR #155 review round 1.

Finding 1 (must fix): `try_split_active` had no production caller —
`pmacs.window.split_horizontal` / `split_vertical`, and therefore
`C-x 2` / `C-x 3`, still went through plain `split_active`. Splitting a
focused panel made the root wrapper's final child a split rather than
`Leaf(side)`, which both `Layout::compute`'s fixed pass and
`document_subtree` key on: the panel band reverted to 1:1 weight
division and an ordinary window ended up living inside it. Both bindings
now route through the guard, and acc26 asserts through the real Lua
path — a direct core call passes with the guard unwired, which is how it
survived the first round.

Finding 2: the armed-drag early return now checks the arming frontend,
so one frontend's in-flight gesture cannot cancel or swallow another's
mouse events. New acc30c.

Finding 3: `paint_mode_line_graphemes`'s doc block was left heading
`paint_divider_segment`; moved back.

Finding 4: a recompile carries no `display`, so it took the raw switch
and duplicated a panel-placed `*compilation*` into the document window.
`start_run` now detects that the buffer already owns the panel slot.
`pmacs.window.buffer` gained an optional window argument so an adopter
can ask without selecting the panel first. New acc19b.

Stage-2 hazard pins the review asked for, both in `src/daemon.rs`:
a fresh attach while LOCAL is focused in a panel inherits LOCAL's
document buffer, and an initial-target bootstrap whose `after-load`
hook creates and selects a panel still reasserts into a document window.

Minor: dropped listview's dead `p.side`; documented `focus_window`'s
caller-validates contract; `jump_back` restores through `focus_window`
so the "every focus change" contract holds; `params` / `resize` default
to the acting frontend's selected window rather than the ambient one;
widened the flexible-division math to u64 intermediates.
