Graduate experimental features to default

 - **Stable Tmux Socket Directory** - Moved tmux sockets from `/tmp/tmux-{uid}/` to `~/.claudio/sockets/` via `TMUX_TMPDIR` to prevent macOS periodic `/tmp` cleanup from killing active tmux servers. `ListClaudioSockets` checks both locations for backward compatibility.
 
 ### Changed
+- **Ship Experimental Features** - Graduated intelligent naming, terminal support, inline multiplan, inline ultraplan, and grouped instance view from experimental to default. These features are now always enabled without configuration. Only subprocess mode remains experimental.
 - **Extract `createTmuxSession()` Helper** - Extracted duplicated tmux session setup from `Start()` and `StartWithResume()` into a reusable `createTmuxSession()` method, eliminating ~40 lines of duplication.
 - **Extract `buildInstanceCallbacks()` Helper** - Consolidated duplicated callback wiring between `newInstanceManager` and `newInstanceManagerWithBackend` into a shared method to prevent sync bugs when adding new callbacks.
 - **Log tmux session option errors** - Replaced silent `_ =` error discards in `createTmuxSession` and recovery paths with Debug/Warn-level logging for better diagnostics.

 Inline planning brings the power of Plan and UltraPlan workflows directly into the standard Claudio TUI. Instead of running a separate command, you can create plans, organize tasks into groups, and execute them all from within your normal session.
 
-> **Note:** This feature is experimental. Enable it via the `experimental.inline_plan` and `experimental.inline_ultraplan` configuration options.
