* perf(terminal): smooth layout drags and faster tab switching
Defer xterm refit during split, sidebar, and host-tree drags while keeping pane containers in sync with live layout measurements. Refactor TerminalLayer into focused sections with TabBridge/memo optimizations and add the terminal host tree sidebar.

* fix(terminal): keep side panels alive and guard session attach races
Prevent terminal boot unmount from leaking backend sessions, keep SFTP/scripts/theme/AI state when switching side tabs, and defer heavy SFTP UI mount so first entry stays responsive.

* Add session activity indicator and store
Introduce a SessionActivityStore (useSyncExternalStore) to track which tabs/workspaces have unread terminal activity. TerminalLayer now strips terminal control sequences, listens for session data, and marks tabs as active when not focused; it also clears activity on focus change and prunes stale IDs. TopTabs consumes the activity map to render a breathing activity dot on session/workspace tabs and adjusts the workspace tab layout to show the dot next to the pane count. Add CSS animation for the activity indicator.
* fix: buffer incomplete escape sequences across data chunks
Add ChunkedEscapeFilter to carry partial ANSI/OSC escape-sequence
tails between successive data chunks, preventing false-positive
activity badges from split control sequences on busy sessions.
Also fix missing trailing newline in sessionActivity.ts.

* fix: remove 256-byte cap on pending escape sequence tails
Long OSC sequences (e.g. clipboard/title payloads) can exceed 256
bytes. Removing the cap ensures they are fully buffered across
chunks instead of being misclassified as printable output.

* fix: buffer OSC tails that end on bare ESC awaiting backslash
OSC sequences terminated with ESC\ can split at the ESC boundary.
Extend the incomplete tail regex to also match an in-progress OSC
sequence ending with ESC (awaiting the closing backslash).
