Use CLIProxyAPI v8 native quotas and readable OpenCode Go accounts

[darfink]

This PR moves the plugin to CLIProxyAPI v8 and replaces its separate quota page with native quota integration.

Changes

• Migrate the SDK dependency and imports from v7 to v8.
• Advertise quota_provider and implement quota.identifier, quota.describe, and quota.fetch.
• Fetch rolling, weekly, and monthly quotas with the credential selected by CLIProxyAPI.
• Keep missing readings unknown, reject invalid values, and redact provider errors.
• Remove the separate quota page and custom management routes.
• Accept an optional name on API key entries and use readable account labels.
• Preserve credential IDs, existing filenames, custom labels, and host metadata.
• Prevent duplicate credential records at cold start.

The plugin version becomes 0.2.0 and requires CLIProxyAPI v8.0.0 or later.
Quota reset remains unsupported.

Scope

Model-specific reasoning metadata and additional Muse Spark/Responses compatibility fixes remain local.
They are not part of this PR. Existing model discovery and protocol behavior from main remain unchanged.

The release notes retain the existing entries. README local build and test commands now use the required debug tag.

Validation

• go test -tags debug ./... passed offline with mock host clients.
• go vet ./... passed.
• The macOS ARM64 C-shared library built with -tags debug -buildmode=c-shared.

No live API calls or local service deployment were part of this verification.

Thanks @darfink. This looks great and I definitely want to merge it.

I'm holding off on merging right now because we need to give users more time to upgrade to v8 before cutting a breaking release, and I'm still on CLIProxyAPI v7 myself.

I'll keep this PR open and merge it once the v8 transition window makes sense.

I pushed another update:

• Updated against the latest main and cleaned up the commit history.
• Explicit model reasoning efforts.

OpenCode Go’s catalog omits reasoning-effort metadata. The plugin now advertises verified options per model and route, with conservative defaults for other models. Model discovery remains dynamic, and metadata supplied by OpenCode Go takes priority.

Also fixed Muse Spark’s Codex tool compatibility using CLIProxyAPI’s SDK tool mapping and removed the unsupported search_content_types field. Requested reasoning controls, media, and usage remain intact. Incompatible historical reasoning and compaction items are dropped for Muse Spark and Grok to prevent replay errors.

I've omitted the fixes for the Muse protocol & the adjusted reasoning efforts for available models - it now only contains the original v8/native-quota integration. However, feel free to merge #12 instead if deemed more fitting.
