openDraft's reuse check was `!target.draft`, dead after first render: createSpawnForm auto-syncs its picked defaults into the leaf's draft once its project load settles, so every empty pane has a non-null draft a second later. `n` and Spawn always split instead of reusing the pane on screen. Reuse now checks only `!target.sessionId`, matching the codebase's own definition of "empty" pane elsewhere. Reusing also drops the leaf's stale form instance so a new seed is read by the rebuilt form instead of being ignored by the old one.
