fix(messages): make conversation text selectable

[jaylfc]

Problem

Reported in #455 (@johny-mnemonic): text in the Messages app can't be selected — neither your own messages nor agent replies.

Root cause

Most app shells in the desktop deliberately set `select-none` for a native-OS feel (Models, Providers, Library, Channels, …). The Messages app relied on the absence of that class to stay selectable, rather than opting in explicitly. That's fragile — any `select-none` added to an ancestor silently makes conversation text unselectable, and it leaves intent unclear.

Fix

Add `select-text` to the message-list container so message content is selectable by design and resilient to future shell changes. One line + an explanatory comment; device-agnostic (same content component on desktop and mobile).

Verification

• `tsc -b` clean.
• Visual confirmation (selecting/copying message text) to be done on a running instance.

Closes #455

This PR enables text selection in the Messages app message list.

Poem

🐰 A tiny tweak, so light and small,
Just text that users now can haul,
Select and copy, message by line—
In conversations, words now shine!
No more locked words, the rabbits say,
Let chatter flow and text convey. ✨
