- Add multi-session Terminal tab with xterm.js (session tabs, close, reconnect)
- Keep terminal mounted across tab switches to preserve sessions
- Persist active tab in URL (?tab=terminal) so refresh stays on terminal
- Buffer keystrokes (50ms) to reduce per-character RPC overhead
- Add WebSocket auth via ?token= query param for browser WS connections
- Enable ws:true in Vite dev proxy for WebSocket support
envd fixes (pre-existing bugs exposed by multi-session terminals):
- Fix getProcess tag Range: inverted return values caused early stop when
multiple tagged processes existed, making SendInput fail with "not found"
- Fix multiplexer deadlock: blocking send to cancelled fork's unbuffered
channel prevented process cleanup. Now uses buffered channels (cap 64)
with non-blocking fallback
Implements a split-panel file browser: directory tree on the left with
path input and breadcrumb navigation, file preview on the right with
line numbers. Binary/large files (>10MB) show a download prompt instead.
Also adds CopyButton component across capsule, snapshot, and template
pages, and fixes pre-existing type errors in StatsPanel and admin
templates page.
- New detail page at /dashboard/capsules/[id] with Stats and Files tabs
- Stats tab shows capsule info card (status, template, CPU, memory, disk,
started, idle timeout) and two stacked Chart.js charts with live values
- Metrics API client with 10s polling and moving-average smoothing
- Capsule ID in list table is now a clickable link to the detail page
- Layout breadcrumb header (Capsules > sb-xxx) with back navigation
- Fix metrics sampler: use v.PID() directly as Firecracker PID since
unshare -m execs (not forks) through the bash/ip-netns-exec/firecracker
chain, so all share the same PID. Removes unused findChildPID.
