Mark Henderson fb31d111ef fix(path-b): dev_server tool dispatch + state-machine transition ...

Two bugs caught by the live end-to-end test:

1. Tool dispatch mismatch.
   Gemini tool name "dev_server_list" runs through executeMcpTool's
   _-to-. converter (toolName.replace(/_/g, '.')) and arrives as
   "dev.server.list". The dispatcher only had cases for "dev_server.list",
   so all four dev_server.* tools 404'd as "Unknown tool".

   The AI gracefully fell back to shell.exec + nohup, so Express still
   ran — but the dev_servers table never got populated and the preview
   URL machinery was bypassed. Add aliases for both underscore and
   fully-dotted forms.

2. State machine never transitioned.
   ensureDevContainer wrote state='provisioning'; nothing ever flipped
   it to 'running'. As a result the idle-sweep (which filters by
   state='running') never saw a candidate to suspend.

   Use the first successful exec as the authoritative liveness signal:
   touchActivity() now also flips provisioning|suspended → running and
   clears suspended_at.

Surfaced by the live trace: AI tried dev_server_list, got 404, fell
back to manually grepping the process table.
