/usage command shows capped credits (100%) in --no-interactive mode but correct overage (153%) in interactive mode

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 15.5 (Apple Silicon)

Expected behaviour

/usage in --no-interactive mode should report the same credit values as interactive mode. When the account is in overage (usage > plan limit), both modes should show the real total (e.g. 15312.32 of 10000).

Actual behaviour

Interactive mode (correct):

Estimated Usage | resets on 2026-08-01 | KIRO POWER
Credits (15312.32 of 10000 covered in plan)
██████████████████████████████████████████████████ 153.1%

Non-interactive mode (incorrect — capped at 100%):

kiro-cli chat --no-interactive --agent meshclaw-lite "/usage"

Estimated Usage | resets on 2026-08-01 | KIRO POWER
Credits (10000.00 of 10000 covered in plan)
████████████████████████████████████████████████████████████████████████████████ 100%

The non-interactive output caps current_usage at the plan limit instead of showing the real overage total. This breaks programmatic consumers that parse /usage output to display credit usage (e.g. editor extensions, dashboards).

Steps to reproduce

1. Have a Kiro Power account that is in overage (usage > 10000 credits)
2. Run interactively: kiro-cli chat then type /usage — shows correct overage (e.g. 15312.32 of 10000)
3. Run non-interactively: kiro-cli chat --no-interactive "/usage" — shows capped 10000.00 of 10000

Also reproducible without --agent:

kiro-cli chat --no-interactive "/usage"

Impact

Any tool that programmatically fetches credit usage via --no-interactive mode cannot detect overage state. The GetUsageLimits API returns the correct data (including current_overages), but the /usage text rendering in non-interactive mode truncates it.
