Cline SDK 0.0.66: free models, agentic compaction default, onRetryAttempt removed

Features

• Free Cline models (cline-free): labeled "(free)", priced at zero; hitting the free tier raises a dedicated limit error including the reset time.
• Agentic compaction is now the default context-compaction strategy.
• Connector sessions persist and auto-reconnect after a daemon or hub restart.
• Plan/act mode, tool auto-approve and compaction mode persist in global settings with cross-process-safe writes, so two hosts no longer clobber each other.
• Built-in provider list generated from models.dev, broadening out-of-the-box coverage; bundled model catalog updated.
• Headless scheduled routines default to auto-approve and no longer ask unanswerable questions.
• Telemetry: task lifecycle events, auth event metadata and request IDs, correct host identity (host_plugin_version, platform) on SDK-pipeline events.

Fixes

• Agentic compaction silently falling back to basic compaction on OpenAI Compatible providers (summarizer built its handler without a base URL and hit api.openai.com).
• Manual compaction budgeting against a 64k fallback instead of the model's real context window.
• Agentic compaction never finding a cut point in tool-heavy transcripts, producing endless "auto-compaction skipped" while context grew — assistant messages are now valid cut boundaries.
• Editor tool preserves a file's existing line endings; CRLF files no longer get mixed endings and failing exact-match edits.
• SAP AI Core sets the metering header and uses the fetch adapter.

Removed

• onRetryAttempt callback removed from ApiHandlerOptions and provider config (documented as never invoked).
• @cline/ui: host-safe theme contract and Markdown exports.
