Add lightspeed extension

[solarisc]

Description

Adds Lightspeed, an independent, persistent file and folder search engine for Raycast on Windows. It recreates the fast search workflow of Everything without requiring Everything, Windows Search, or another external search service.

Lightspeed builds its own SQLite/FTS index, keeps it current with debounced filesystem watchers, and returns saved results immediately across Raycast launches. It indexes fixed drives by default while allowing users to restrict roots and exclusions.

Search features

• Instant filename and path search
• ext:, path:, file:, folder:, and regex: filters
• Quoted terms, negation, and wildcards
• File, folder, document, image, audio, and video scopes
• Open, reveal, open-with, and copy actions

Disk safety

Lightspeed never modifies indexed files. All writes stay inside its private SQLite index. Incremental changes are batched, WAL growth is limited, and full reconciliation runs at most weekly unless requested manually.

Verification

• Initial full-drive indexing completed successfully in Raycast
• Live search measured at approximately 1 ms against an index of about 1.46 million entries
• Incremental create, rename, and delete behavior covered by tests
• npm test, npm run lint, and npm run build pass

Screencast

Checklist

• I read the extension guidelines
• I read the documentation about publishing
• I ran npm run build and tested this distribution build in Raycast
• I checked that files in the assets folder are used by the extension itself
• I checked that assets used by the README are placed outside of the metadata folder
