fix: handle GLM model JSON array output format

[mikij]

Context

GLM-4.7 models (via Kilo Gateway) output code as JSON arrays instead of plain text:
[{@angular/core: import { ComponentFixture }, @angular/testing: import { render }}]
This format is unreadable in the UI and breaks normal text display.

Implementation

Added a JSON array to plain text conversion in ProviderTransform.normalizeMessages() (packages/opencode/src/provider/transform.ts):

1. Condition: Only applies to kilo provider with z-ai/glm model IDs
2. Logic: Detects string content starting with [ and ending with ], parses as JSON, converts array of objects to key: value format
3. Result: [{"@angular/core": "import {...}"}] → @angular/core: import {...}
   The transform:

• Handles nested objects (stringifies them)
• Preserves whitespace handling
• Only processes assistant role messages with string content
• Gracefully falls back for invalid/non-matching JSON

[{"@angular/core": "import { ComponentFixture }"}]	@angular/core: import { ComponentFixture }

How to Test

1. Start a code session with z-ai/glm-4.7 model
2. Ask the model to write code (e.g., "Write an Angular component test file")
3. Verify the response displays as readable text, not JSON array structure
