feat(agent-source): add Windsurf and Cline adapters

[Timelovers]

Description

Add agent-source adapters for Windsurf (Codeium) and Cline (VS Code extension) so Memmy can import conversation history from these tools.

Windsurf

Reads conversation JSON files from ~/.codeium/windsurf/conversations/. Each conversation is a JSON array of turns with role and content fields.

Cline

Reads task JSON files from the VS Code globalStorage directory (tasks/). Each task file contains a messages array with role, say/text/content fields.

Changes

• New agent-source/windsurf/ — adapter, session-discovery, transcript-reader, index
• New agent-source/cline/ — adapter, session-discovery, transcript-reader, index
• agent-paths.ts — add resolveWindsurfDataDirectory and resolveClineDataDirectory
• builtin-agent-source-registry.ts — register both adapters
• Tests — 6 unit tests (3 per adapter: descriptor shape, detect false on missing dir, custom config)

Both follow the existing adapter pattern (Claude Code / Opencode).

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

• Unit Test — 6 tests covering descriptor, detect(), and custom configuration

Received. We anticipate incorporating it into the next version, with plans for testing and releasing v1.0.5 @Timelovers

Thanks for the contribution. We tested this PR against real local installations, but it is not ready to merge yet:

• Cline initialization crashes with TypeError: runtime.platform is not a function.
• Cline CLI 3.0.52 stores sessions under ~/.cline/data/sessions, but the adapter detects 0 sessions. Real message content is an array, which also crashes the secret redactor.
• Windsurf is now Devin Desktop. Current sessions are stored as ACP events under ~/Library/Application Support/Devin/User/acp-events, while this PR expects ~/.codeium/windsurf/conversations/*.json. Testing against the real installation detected 0 sessions.
• The PR also has TypeScript errors, including the nonexistent readDirectoryEntries export.

Please verify both adapters using sanitized fixtures from real installations and add discovery/reader tests. Requesting changes for now.

Thanks for the detailed review @hijzy. Pushed fixes:

• Cline: fixed path to ~/.cline/data/sessions, removed runtime.platform(), added array content handling
• Windsurf → Devin Desktop: updated path to ~/Library/Application Support/Devin/User/acp-events
• Removed nonexistent readDirectoryEntries import

Would appreciate another look when you have a chance.
