feat(ui): delete sessions from Control UI

CHANGELOG.md

@@ -27,6 +27,7 @@
 - TUI: show provider/model labels for the active session and default model.
 - Heartbeat: add per-agent heartbeat configuration and multi-agent docs example.
 - UI: show gateway auth guidance + doc link on unauthorized Control UI connections.
+- UI: add session deletion action in Control UI sessions list. (#1017) — thanks @Szpadel.
 - Security: warn on weak model tiers (Haiku, below GPT-5, below Claude 4.5) in `clawdbot security audit`.
 - Apps: store node auth tokens encrypted (Keychain/SecurePrefs).
 - Cron: isolated cron jobs now start a fresh session id on every run to prevent context buildup.
