feat(web): show deprecated badge for orchestrator in mode selector

[IamCoder18]

Context

The Orchestrator agent was deprecated in Kilo-Org/kilocode#7888 since other agents support multiple agents natively. It also has problems calling various modes, and was confusing people.

Closes #3681

Implementation

Added a visual "Deprecated" warning badge to the Orchestrator agent in the Cloud web mode selector (ModeCombobox). Extended the ModeOption type with an optional deprecated flag, marked orchestrator as deprecated in NEXT_MODE_OPTIONS, and rendered a new Badge warning variant next to deprecated entries. This surfaces the deprecation consistently across all Cloud agent dropdown surfaces on app.kilo.ai/cloud (new session panel, chat input, mobile toolbar popover).

Verification

• Open the Cloud web app, open the mode selector, and confirm "Orchestrator" shows a yellow "Deprecated" pill badge.
• Verify other modes (Code, Plan, Debug, Ask) do not show the badge.

Visual Changes

Reviewer Notes

• The warning Badge variant follows the existing beta/new pill pattern (rounded-full with tinted background + ring).

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The PR cleanly adds a deprecated field to ModeOption and renders an amber-colored "Deprecated" label for the orchestrator entry in NEXT_MODE_OPTIONS, with no security, runtime, or logic issues.

Note: The PR description references a "Badge warning variant" and "yellow pill badge", but the actual implementation uses an inline <span> with text-amber-400/80 styling — no Badge component is used. This is a description/implementation mismatch but doesn't affect correctness. The visual result (amber-colored text label) is functionally equivalent.

[eshurakov]

thank you for the PR, I've updated the design to a more subtle version

Hey @eshurakov! The CI is failing due to missing Vercel secrets (refer to this comment), but I was hoping this, as well as much other PR which are being blocked in the say way by Vercel CI, could get merged!
