feat(files): move workspace indexing and search to native for saf/files

[bajrangCoder]

Summary

Moves file indexing and project-wide search for SAF and file:// workspaces to the Android native layer.

This prevents large workspaces, such as Termux home, from creating a complete file tree in the WebView.

Changes

• Added a native SQLite workspace index.
• Added paginated native filename queries.
• Added the new asynchronous fileIndex plugin API.
• Migrated Quick Open to native queries.
• Migrated project-wide search to native root-based search.
• Batched native search results to reduce Cordova bridge callbacks.
• Removed progress callbacks from individual file reads.
• Skips files and directories that return permission errors.
• Fixed project search after closing one folder and opening another.
• Fixed folder exclusion matching, including node_modules.
• Prevented recursive indexing of Termux ~/storage.
• Kept FTP, SFTP, and custom storage providers on the JavaScript fallback.

Breaking changes

acode.require("fileList") is deprecated.

It now contains files from non-native providers only. Plugins using it for SAF or file:// workspaces must migrate to:

const fileIndex = acode.require("fileIndex");
const result = await fileIndex.query({
  roots: [workspaceUrl],
  text: "filename",
  limit: 200,
});

Differences from fileList:

• fileIndex is asynchronous.
• Results are flat metadata records instead of Tree objects.
• Large results use cursor pagination.
• Native search can emit batched search-results events.

The native index database version is also updated. Existing generated indexes will be rebuilt automatically.

Compatibility

• SAF and file://: native index and search.
• FTP and SFTP: existing JavaScript fallback.
• Low-level sdcard.workspaceSearch() keeps single-result events unless batchResults: true is provided.

Greptile Summary

This PR moves local workspace indexing and search into the Android native layer. The main changes are:

• Adds a SQLite index for SAF and file:// workspaces.
• Adds asynchronous filename queries and paginated results.
• Moves Quick Open and project search onto the native index.
• Batches native search events across the Cordova bridge.
• Keeps remote and custom providers on the JavaScript fallback.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• JavaScript and native method signatures align.
• Search consumers handle both individual and batched events.
• Async Quick Open and search paths reject stale results.

src/lib/fileIndex.js	Adds the asynchronous JavaScript API for native scans, queries, searches, cancellation, and index maintenance.
src/sidebarApps/searchInFiles/index.js	Moves eligible project searches to the native index and queues batched results for rendering.
src/palettes/findFile/index.js	Moves Quick Open for native workspaces to asynchronous paginated filename queries.
src/components/inputhints/index.js	Adds debounced dynamic hint generation with stale-response guards.
src/lib/fileList.js	Keeps tree indexing for fallback providers and routes local workspace updates to the native index.
src/lib/openFolder.js	Reorders folder removal so native index cleanup runs while the root is still registered.
src/plugins/sdcard/www/plugin.js	Exposes the new native workspace operations through Cordova.
src/plugins/sdcard/index.d.ts	Adds declarations for native queries and batched search events.
