Rewrites the page around the dual-mode right panel (Anatomy by default,
Monaco when the user clicks edit), the redesigned Command Center action
bar, the new container row layout with status badges and live stats, the
Structured / Raw terminal logs toggle, the Git Source toolbar button, and
the opt-in diff preview. Drops the obsolete persistent embedded terminal
section. Preserves the #diff-preview-before-save and #log-viewer anchors
referenced from settings.mdx and global-observability.mdx. Replaces
editor-overview.png and container-exec-modal.png with fresh captures
against v0.72.0 production at 1920x900 dark theme; renames container
-actions.png to containers-list.png; adds command-center.png and
editor-edit-mode.png. PII scrubbed (host paths normalized) and the
compose-diff-preview/diff-modal.png shared asset is left untouched after
visual diff against the live UI showed no chrome change.
* fix(container-exec): harden with security fixes, validation, and test coverage
- Enforce admin role at WebSocket upgrade for container exec sessions
- Validate container is running before creating exec
- Fix bash-to-sh fallback (move .start() inside try/catch)
- Register container-exec as a capability for fleet visibility
- Add standard and diagnostic logging for exec lifecycle
- Fix false Admiral license claim in API docs
- Fix design system violations in BashExecModal (hardcoded colors)
- Remove duplicate legacy xterm dependencies
- Add 18-test suite covering auth, validation, fallback, and cleanup
* fix(container-exec): use correct Duplex type for exec stream
The stream variable was typed as NodeJS.ReadWriteStream, which lacks
.destroy(). Dockerode's Exec.start() returns stream.Duplex per its
type definitions. This caused tsc to fail while Vitest (which skips
full type checking) passed.
