* feat(stack-view): per-container health strip and structured logs viewer
Replaces the flat container list with a per-container health strip showing
healthcheck state, uptime, port mapping with an open-app link, and live
cpu/memory/network sparklines fed by a 60-sample ring buffer on the stats
WebSocket.
Adds a structured logs viewer that parses docker timestamps (emitted by the
-t flag on the logs stream) and classifies each line by level. Rows render
as a DOM grid with filter pills (all / info / warn / err with count),
following indicator, and plain-text download. A segmented toggle switches
between the structured viewer and the original xterm view; the choice is
persisted in localStorage.
* fix(stack-view): disable no-control-regex for ANSI escape pattern
ANSI escape sequences start with ESC (0x1B), which is a control character.
The regex is intentional and cannot be rewritten without it.
