[codex] Add Crof provider

[baanish]

Summary

Adds Crof as an API-key provider in CodexBar. The new provider calls GET https://crof.ai/usage_api/ with a bearer token, parses credits, requests_plan, and usable_requests, and renders request quota as the primary usage row with credit balance as the secondary row.

The menu keeps the exact request count visible on the right, infers the daily reset from midnight America/Chicago based on Crof's current support guidance, and links to the Crof dashboard. The provider also supports CROF_API_KEY, CROFAI_API_KEY, and the existing ~/.codexbar/config.json API-key flow.

Testing

• swift test --filter 'CrofUsageFetcherTests|CrofMenuCardTests|CrofProviderImplementationTests|ProviderIconResourcesTests'
• pnpm check
• git diff --check HEAD~1 HEAD

Notes

• Full swift test was not used as the final gate because the existing Mistral date parser test is failing independently on this machine (MistralUsageParserTests.swift:69, expected month 11, got 10).
• Crof's API does not currently return reset metadata, so the reset is based on what they said in Twitter DMs

Avoid encoding Crof credit balance as a reset string

Storeing Crof credits in secondary.resetDescription while secondary.resetsAt is nil makes generic renderers print a misleading reset message (e.g., "Resets 10 credits") because UsageFormatter.resetLine prepends "Resets" whenever only resetDescription is present (Sources/CodexBarCore/UsageFormatter.swift, resetLine). This affects paths that were not given Crof-specific overrides (notably CLI/text renderers), so users can see credit balance presented as if it were a reset time.
