The extension now pushes tab changes to tabctl in real time. Previously, tools built on tabctl (status bars, launchers, tab strips) had to poll to notice new, closed, moved, or renamed tabs. The extension now sends a lightweight, debounced notification whenever your tabs change, so those tools update the moment it happens instead of on a timer.

• Emits an update signal on tab create, close, move, activate, and attach/detach
• Also fires when a tab's title, URL, or pinned state changes (favicon and load-progress churn is ignored, so no needless refreshes)
• Rapid bursts (session restore, "close other tabs") are coalesced into a single notification

Fully backward compatible: no new permissions, and the wire protocol is unchanged. Requires tabctl 2.1.0 or newer on the command-line side to take effect; with an older tabctl the extension behaves exactly as before.

Reworks how the extension communicates with the tabctl command-line tool for reliability, and adds a version handshake so the two stay in sync.

• If the tabctl command-line package is older than the extension, the extension shows an out-of-date indicator (a badge on its toolbar icon).
• Cleaner internal tab identifiers and more robust tab data.
• Groundwork for future features.

Requires the tabctl 2.0.0 command-line package. Please update BOTH the extension and the command-line tool to 2.0.0 together

More reliable tab commands and clearer error reporting: operations no longer hang on failure, stale-tab actions report errors instead of failing silently, and opening multiple URLs no longer aborts on a single bad URL.

Window focus on tab activation: When activating a tab via tabctl activate, the browser window is now focused automatically, bringing it to the foreground across virtual desktops
