* fix(terminal): a pane that loses its attach to another connection attaches to the winner When a terminal pane reconnected to a saved process that had exited, and another writer re-bound the pane meanwhile (most often the window's own session save), main threw terminal_pane_owner_changed. The window showed it as a raw red banner over a pane that was otherwise working, and nothing cleared it. Main now re-resolves the pane's owner once and attaches to it, with fresh absence evidence even when only the saved binding changed. Retiring a dead id's binding is fenced on its incarnation so it can never clear a newer process that reused the id. A second loss is still reported; the window asks once more for a local pane (never a fresh launch) and otherwise shows the existing reconnect banner with Retry instead of the raw code. Tracked in STA-4139. * refactor(terminal): move the stable-pane attach step into its own file (max-lines) * fix(terminal): fence an absent owner's retirement on an explicit incarnation, not the binding's own field * Complete bounded pane ownership recovery through host publication * Apply repository style rules to pane recovery changes * fix: preserve terminal adoption type contracts * fix: complete terminal recovery ownership and acceptance contracts * fix: keep terminal registration evidence with its candidate * fix: satisfy terminal recovery lint gates * fix: consolidate terminal recovery imports * test: explain bounded terminal fixture assertions * test: handle optional pane binding maps in assertions * fix: scope remote pane ownership refresh to recovery epoch * fix: reject remote pane replies after recovery epoch ends * Fix static checks for pane recovery * Reuse session partition assignment in binding retirement * fix: acquire returned terminal receipt before rejecting early exit * Release superseded terminal spawn preparation before retry * test: type preparation cleanup callbacks as functions * test: initialize telemetry classifier in preparation collision cases * test: identify preparation resources in reentry assertions * fix(terminal): let a recovered pane replace the binding its host proved dead Reopening an agent terminal whose process had exited showed "Orca couldn't verify this terminal's owner", and the next relaunch lost the tab. The pane operation proved the old PTY absent, but a window session save wrote that dead binding back before the fresh commit, and the commit treated it as a rival owner. The refused candidate was then shut down without an intentional-stop mark, so its exit retired the whole tab. The operation now carries its absence proof into the fresh launch, and both the pre-launch owner check and the commit accept a replay of that dead binding. A different or unproven owner is still contention. Discarded candidates are marked as replaced, so their exit keeps the tab. * test(terminal): type the discard test's runtime mocks * fix: expose reconnect for retained pane recovery * test: expect replaced stop for discarded fresh terminals * fix(terminal): type the absent owner's retirement fence after the main merge * test(terminal): follow main's Reconnect handler in the pane binding ownership test
