feat: promote split survivor into the main pane on primary exit (#121)

* feat: promote split survivor into the main pane on primary exit

When the primary (left) pane's shell exits and a split pane is alive,
closePrimaryPane now MOVES the surviving split pane into the main `surface`
slot instead of leaving it parked in `splitSurface`:
- survivor.promoteToPrimaryPane() flips its split-role flag (new TerminalSurface
  method) so its pwd/title reports route to the main fields
- surface = survivor, splitSurface = nil, splitFocused = false, hasSplit = false
- splitCwd/splitTitle/splitForegroundCommand migrate up to currentCwd/oscTitle/
  foregroundCommand, then the split fields clear

The collapsed session is now indistinguishable from a fresh single pane, so it
is addressed as the MAIN/left pane everywhere: session.type/session.text --pane
left (and omitted) reach it, session.focus errors (no split), {AGT_PANE} reports
left, and a later session.split opens a fresh RIGHT pane beside the survivor
instead of displacing it. This makes the {AGT_PANE} round-trip honest (left maps
to a pane session.type can reach), superseding the interim "promoted survivor
reports right" contract.

Docs updated to match (CustomCommand.pane, keymap.md, control-api.md); the
promoted-survivor e2e now expects left; host-free promotion test rewritten.

Review hardening (post-cherry-pick correctness fixes):
- closeSplitPane: a promoted survivor keeps the split pane's onExit, so its own
  exit routed here; tightened the guard to close the session (not collapse a
  nonexistent split) when there is no genuine two-pane split — fixes a
  zombie-session leak on the promoted pane's own exit.
- makeSplitSurface.onFocusChange now sets splitFocused = view.isSplitPane (was
  hardcoded true), so a promoted survivor no longer re-raises splitFocused —
  which otherwise masked its migrated title and mis-routed focus after a re-split.
- focusedCwd/focusedOscTitle guard on splitFocused && splitSurfa... (continued)
