fix(acp): normalize model ids with /enabled /disabled status suffixes

[whitelonng]

Summary

• Some ACP agents (e.g. CodeBuddy) report each model twice with a status suffix on the id (glm-5.1/enabled, glm-5.1/disabled) and label (GLM-5.1 (enabled)). These raw ids flowed untouched into the model selector, setModel requests, handshake-derived defaults and the persisted preferredModelId, causing duplicate dropdown entries and model switches that always fell back to the first model.
• Adds normalizeAcpModelInfo / normalizeAcpModelId (packages/desktop/src/renderer/utils/model/normalizeAcpModelInfo.ts) which strips the suffixes and deduplicates by clean id, preferring the /enabled variant when both are present.
• Applies the normalization at every point where ACP model info enters the renderer: getModel/setModel responses and acp_model_info stream events (useAcpModelInfo), handshake fallbacks (useAcpModelInfo, useDetectedAgents, useGuidAgentSelection, CreateTaskDialog, createConversationParams, teamCreateModelResolver), and saved preferredModelId reads — so already-polluted persisted data is also repaired on read.

Fixes #3297

Test plan

• New unit tests in tests/unit/renderer/normalizeAcpModelInfo.test.ts covering suffix stripping (case-insensitive), dedup with /enabled preference, clean-list passthrough, vendor-prefixed ids (vendor/model-name untouched), and empty-label fallback
• bunx vitest run — 1377 tests pass
• bunx tsc --noEmit, bun run lint, bun run format, i18n checks pass
• Manual: with a CodeBuddy ACP agent, verify the model dropdown shows each model once with a clean label, and switching to a non-default model sticks across subsequent turns
