feat: do file-listing and index on java for file:/// and saf locations

[bajrangCoder]

• do file listing, indexing(if asked) on native java side for file:/// and saf location to improve the search speed and ui smoothness even searching in big projects on lower end devices
• improve getSurrounding to show meaning full snippet in search
• tweaked ui a bit for nicer ux
• show progress and status when searching
• improve binary detection

Greptile Summary

This PR offloads file-tree listing and search/replace to native Java (WorkspaceIndex.java) for file:/// and SAF content:// workspaces, eliminating the previous JS-worker search index in favour of a SQLite-backed cache and a Cordova bridge. UI improvements include richer match snippets, line-number gutters, and a redesigned result header.

• WorkspaceIndex.java (~1 400 lines): new SQLite helper managing workspace scanning (files table), optional content indexing (content table), and multi-file search/replace with glob filtering, binary detection, and Cordova event streaming.
• fileList.js / index.js: JS layer updated to route file: and content: URLs through the native scan/search path while keeping the existing worker path for other schemes; stale-job protection uses a searchVersion counter threaded through every async callback.
• cmResultView.js / worker.js / styles.scss: display polish — full-line snippets with ellipsis, line-number prefix marks, ghost-text guard on decorations, and chevron/count repositioning.

Confidence Score: 5/5

Safe to merge; the functional logic is sound and no data-loss or correctness bugs were found.

The core scan/search flow is well-structured: the files table delete-and-repopulate is wrapped in a transaction so a mid-scan failure leaves the workspace consistent. Version-gated callbacks prevent stale native jobs from completing against a newer search. The two issues found are storage hygiene nits — orphaned content rows for deleted files accumulate between explicit clear() calls, and the unused lower_text column wastes roughly one text blob per indexed file.

src/plugins/sdcard/src/android/WorkspaceIndex.java — specifically the runScan method (content table cleanup) and indexFile (lower_text column).

Important Files Changed

Filename	Overview
src/plugins/sdcard/src/android/WorkspaceIndex.java	New 1,428-line file implementing native workspace scanning, indexing (SQLite), and search/replace for file:/// and SAF content:// URIs. Two minor storage issues found: content table orphaned rows accumulate on re-scan, and the lower_text column is written but never read.
src/lib/fileList.js	Adds native workspace scan path via getAllFilesNative/addNativeEntries and a removeRootTree helper for cascading cleanup; excluded directory handling is consistent with the existing JS path.
src/sidebarApps/searchInFiles/index.js	Replaces the JS-worker search index with native Java search; introduces activeSearchTasks/activeReplaceTasks counters, version-gated stale-event guards, and finishSearchTask/finishReplaceTask helpers. Logic appears correct for concurrent native+worker split.
src/sidebarApps/searchInFiles/worker.js	Updates getSurrounding to emit full line context (up to 160 chars) with ellipsis trimming, and adds line field to match objects for display parity with native results.
src/sidebarApps/searchInFiles/cmResultView.js	UI rework: chevron moved to end of header, count badge driven by fileInfo.count, ghost-text flag suppresses decorations during loading, and line-number prefix detection prevents false match highlights.
src/plugins/sdcard/src/android/SDcard.java	Routes five new workspace * action strings to WorkspaceIndex; otherwise unchanged.
src/utils/binaryExtensions.js	Adds textExtensionSet and isTextPath export; isBinaryFile now returns false early for known-text extensions before reaching the binary MIME check.
src/sidebarApps/searchInFiles/styles.scss	Visual polish: tighter padding, line-number gutter style, chevron repositioned to right of header, striped row backgrounds replaced with border separators.
src/lib/openFolder.js	Adds FileList.remove(_path) call on folder close to ensure the cascading removeRootTree cleanup runs when a workspace is removed.
src/plugins/sdcard/index.d.ts	Adds TypeScript declarations for WorkspaceFileEntry, WorkspaceEvent union, and the five new SDcard workspace methods.
bun.lock	Bumps dompurify, markdown-it, and linkify-it; adds a mermaid-scoped dompurify entry.
