OrcaWinandOrcaWin e599d924bd fix(editor): stop Close All / Close Others freezing the renderer on large tab sets (#12404)
* fix(editor): stop Cmd/Ctrl+Shift+T reopening a phantom editor tab

`openFile` honored a recently-closed snapshot's `reopenId` whenever no
open file currently held that id, without checking whether the same
(path, mode, owner) was already open under a different id. Editor ids
are not symmetrical across worktrees: the first worktree to open an
absolute path gets the bare path as its id, and any other owner of the
same path gets a namespaced `editor:<wt>:<runtime>:<path>` id. So a
snapshot captured under one shape could be restored while the live tab
carried the other.

When that happened `openFile` took the `existing` branch and mapped over
`openFiles` looking for the stale id, matching nothing — no OpenFile was
created or updated — yet it still set `activeFileId`, the per-worktree
active id, the tab bar order and a unified tab entity to that stale id.
The user got a tab rendering nothing and a dangling active editor.

Resolve the id from the already-open file whenever one exists, so capture
and restore agree on canonicalization. This is a no-op for the non-reopen
path, where `resolveEditorFileIdForOwner` already returns `existing.id`
via the identical predicate.

* fix(editor): make Close All linear instead of cubic in tab count

closeAllFiles resolved a reopen position for every closing tab by calling
getRecentlyClosedTabPosition, which itself rescanned the worktree's tab-bar
order and group membership with a nested find per entry. That made the whole
bulk close O(N^3) in open editor tabs, and because it runs inside a synchronous
zustand set() the renderer is blocked for the entire duration: measured against
the real store, 500 tabs took 1.2s and 1000 tabs took 13.0s of frozen UI.
Sessions that accumulate tabs — long SSH/relay work, a mirrored host republishing
open files, a folder workspace opened wide — hit this on a single menu click.

Hoist the per-tab rescans into one precomputed index. The new
createRecentlyClosedTabPositionIndex builds tab-bar, unified-tab, and group
lookups in a single linear pass over the worktree's state, then answers each
position query in O(1); getRecentlyClosedTabPosition now delegates to it so
single-tab callers keep identical behavior. Positions, reopen order, and the
tab-bar/group indices recorded by #12236 are unchanged — first-occurrence wins
everywhere, matching the indexOf/find scans this replaces.

Position derivation moves to its own module so recently-closed-tabs.ts stays
under the max-lines limit without a suppression; existing importers are
unaffected via re-export.

Same measurement after the change: 500 tabs 44ms, 1000 tabs 142ms, and the
instrumented scan count drops from 503,000,500 to 4,000 at N=1000.
