remove duplicate discount text

Remove duplicate discount info from Auto model tooltip

What was removed

The modelTooltip for AutoChatEndpoint previously included discount information appended to the tooltip text (e.g., "Auto is given a 10% discount."). This has been simplified to always show the base description:

"Auto selects the best model for your request based on capacity and performance."

Why it was removed

The discount value is already shown via the modelDetail variable, which populates two fields on the model:

• detail — displayed as the description/detail line in the model picker
• multiplier — displayed as the multiplier badge for Auto models, and also rendered in the model hover content (getModelHoverContent in chatModelsWidget.ts)

The removed tooltip code and the remaining modelDetail code use the same logical checks, just expressed differently:

Condition	Removed tooltip code	Remaining modelDetail code
No discount (0%)	isNoAuthUser || (low === 0 && high === 0) → no discount text	high === low && low !== 0 fails → no detail set
Single discount	low === high (non-zero) → "{low}% discount"	high === low && low !== 0 → "{low}% discount"
Discount range	else → "{low}% to {high}% discount"	high !== low → "{low}% to {high}% discount"

Since the discount info is already visible in the model picker description, showing it again in the tooltip was redundant.

Pull request overview

This PR removes redundant discount messaging from the AutoChatEndpoint tooltip in the Copilot model picker, relying on the existing modelDetail/multiplier UI to communicate discount information.

Changes:

• Simplified AutoChatEndpoint tooltip text to always show the base “Auto selects…” description.
• Removed conditional tooltip suffixes that repeated discount details already surfaced elsewhere in the model picker/hover UI.
