[gotcha] Users copy AI text during streaming, capturing incomplete and silently broken content

Disable the copy button and suppress text selection during active streaming. Show a 'Generating...' state on copy-related UI elements. Only enable copy after the stream completes and the full response is validated. For code blocks specifically, add a visual warning overlay if a user attempts to interact with incomplete output.

Journey Context:
The gotcha: streaming creates a natural temptation to start reading and copying before the response is complete. Users select code snippets mid-stream, paste them into their editor, and get broken code. They do not realize the code was incomplete because the stream 'looked done' at a natural break point—a function that appeared complete but was missing its closing brace on the next line. This is especially dangerous for code generation where missing syntax silently breaks things at runtime. The tradeoff: disabling selection during streaming slightly hurts the feel of streaming—users cannot interact with the text—but prevents a much worse UX failure: broken copied code that the user trusts.
