fix(runtime): resolve folder workspace file selectors

[bennewell35]

Summary

• resolve folder workspace selectors for runtime file operations without broadening generic git/worktree selector behavior
• preserve SSH connection routing for remote folder workspace file reads
• add local and SSH regression coverage for folder workspace file explorer paths

Addresses the file explorer selector_not_found portion of #6357.

Tests

• pnpm exec vitest run --config config/vitest.config.ts src/main/runtime/orca-runtime.test.ts -t "reads file explorer paths for a|routes SSH folder workspace file explorer|folder workspace"
• pnpm exec vitest run --config config/vitest.config.ts src/main/runtime/orca-runtime-files.test.ts src/main/runtime/orca-runtime-files-watch.test.ts
• pnpm exec oxlint src/main/runtime/orca-runtime.ts src/main/runtime/orca-runtime-files.ts src/main/runtime/orca-runtime.test.ts src/main/runtime/orca-runtime-files.test.ts src/main/runtime/orca-runtime-files-watch.test.ts
• pnpm run typecheck:node

📝 Walkthrough

Walkthrough

The runtime service now exposes resolveRuntimeFileTarget, which returns a worktree and optional connectionId from folder-workspace scope resolution or worktree lookup. Runtime-file commands, search/list operations, and file-explorer path resolution now consume that target, and the tests update their mocks and coverage.
