Clean break, no compatibility alias. Renames the product name, the CLI
binary (`ccam` -> `agenthub`), the env var prefix (`CCAM_` ->
`AGENTHUB_`), the Prometheus metric namespace (`ccam_*` ->
`agenthub_*`), the tmux session prefix (`ccam-lane-<id>` ->
`agenthub-lane-<id>`), the per-repo runtime profile directory
(`.ccam/profile` -> `.agenthub/profile`), the lanes state root
(`~/.claude/ccam-lanes` -> `~/.claude/agenthub-lanes`), the bundled
plugins (`plugins/ccam*` -> `plugins/agenthub*`) and their slash
commands (`/ccam-doctor` -> `/agenthub-doctor`, `/ccam:*` ->
`/agenthub:*`).
Because there is no alias, an existing install has to be updated by
hand: rename its `.ccam/profile` directory and any `CCAM_*` variables,
and reinstall the plugin under its new name.
Two other name families are deliberately left alone here, since they are
not just strings: the `Claude-Code-Monitor` repository/marketplace name,
and the `agent-dashboard` npm package plus its `~/.claude/agent-dashboard`
runtime directory, which holds the live database and needs a migration
rather than a rename.
Verified: server 1406/1406, client 459/459, `grep -i ccam` clean across
tracked files, `openapi.yaml` regenerated (95 paths, unchanged count).
closeWebSocket() nulls both WebSocketServer references but cannot unregister
the `server.on("upgrade")` listeners that initWebSocket/initPtyWebSocket
installed on the shared http.Server. An upgrade landing in that window threw
TypeError: Cannot read properties of null (reading 'handleUpgrade')
from the listener — unhandled, so it killed the process mid-SIGTERM instead of
letting it exit gracefully, and no server came back up. Observed in
runtime/server.log right after a restart, with the dashboard then showing
"Mất kết nối" and nothing else.
The previous commit's TerminalView reconnect makes this near-certain rather
than rare: every open run console re-attaches to /ws-pty every 1.5s, so a
shutdown almost always has an upgrade in flight. Both listeners now destroy
the socket when their server is gone; clients retry, which is the correct
answer during a shutdown.
Regression test uses a real http.Server and raw upgrade requests — without the
guard the process dies and the test run hangs rather than reporting a failure.
