Improve Kiro credits and account visibility

[solnikhil]

Summary

Kiro currently does not surface enough account and credit detail in CodexBar. The menu bar/card/settings views should make it clear which Kiro account is signed in, how the user authenticated, what plan is active, how many credits remain, whether bonus credits are active, and whether overages are enabled.

Desired behavior

• Show Kiro credits left, not only percentage usage.
• Show Kiro account email and auth method, e.g. Auth: Google.
• Normalize Kiro plan labels, e.g. KIRO FREE -> Kiro Free.
• Show regular credits, bonus credits, reset/expiry details, and overage status when available.
• Add Kiro-specific menu bar display options:
  • Automatic
  • Hidden
  • Credits left
  • Percent left
  • Credits + percent
  • Used / total
• Keep Kiro plan data separate from shared provider identity fields.

Scope

Use local CLI output only:

• kiro-cli whoami
• /usage
• best-effort /context

No private Kiro web/API probing should be added for this first pass.

Notes

/context can be parsed for future use, but context window details do not need to be shown in the menu card by default.

Fixed by PR #933, merged as 66b8277.

What changed:

• Kiro usage now shows account/auth details, plan labels, credit and bonus-credit balances, and overage state
• Kiro has dedicated menu bar display options for credits, percent, both, or used/total
• the Kiro parser handles current CLI usage, whoami, and context output variants

Verification:

• swift test --filter KiroStatusProbeTests --filter KiroMenuCardModelTests --filter StatusItemBalanceDisplayTests --filter MenuCardModelTests

Fixed by merged PR #933 on main in 66b8277d, with changelog in 1880c902.

What landed:

• Added focused parser, menu-card, and status-item display coverage.
