[Bug] Output token limit settings not being applied, agent output capped at 32k tokens

## Bug Description

Environment variables for output token limits are not being respected by agent subprocesses. Agents consistently
hit the 32,000 token output limit despite explicit configuration attempts.

## Expected Behavior

Agents should respect the CLAUDE_CODE_MAX_OUTPUT_TOKENS environment variable and allow up to 100,000 output
tokens as configured.

## Actual Behavior

• Agents process for 20+ minutes
• Hit 32,000 token output limit
• All processing output is lost
• Configuration variables have no effect

## Impact

Critical for production workflows:

• Loss of valuable synthesized information after long processing
• Wasted computational tokens (input tokens consumed, no output saved)
• Forces manual work-splitting or content reduction workarounds
• Makes agent-based consolidation workflows unreliable

## Configuration Attempted

Tried setting in all configuration files (project-level and global):

```json
{
"env": {
"MAX_MCP_OUTPUT_TOKENS": "100000",
"CLAUDE_CODE_MAX_OUTPUT_TOKENS": "100000",
"MAX_THINKING_TOKENS": "20000"
}
}

Also attempted via PowerShell:
[System.Environment]::SetEnvironmentVariable('CLAUDE_CODE_MAX_OUTPUT_TOKENS', '100000', 'User')

Variable confirms as set:
PS> [System.Environment]::GetEnvironmentVariable('CLAUDE_CODE_MAX_OUTPUT_TOKENS', 'User')
100000

But agents still fail at 32K output tokens.

Steps to Reproduce

1. Set CLAUDE_CODE_MAX_OUTPUT_TOKENS=100000 in config or environment
2. Launch agent with Task tool for large synthesis task (e.g., consolidating 1,200 lines into single deliverable)
3. Agent processes for 20+ minutes
4. Observe error: "API Error: Claude's response exceeded the 32000 output token maximum"
5. Verify config shows 100000, but limit is ignored

Environment

• Platform: win32
• Terminal: PowerShell
• Claude Code Version: 2.0.30
• Feedback ID: ca11bc04-3729-4a2a-8c62-f42c7711e180

Related Context

Error occurs specifically when using Task tool with subagent types (e.g., general-purpose, custom agents). The 32K
limit appears hardcoded for agent subprocesses and doesn't inherit parent environment configuration.

Suggested Fix

Ensure agent subprocesses inherit or explicitly receive the CLAUDE_CODE_MAX_OUTPUT_TOKENS environment variable
from:

1. Parent process environment
2. Project .claude/config.json
3. Global config ~/.claude/config.json
