Enable multi-download: group batch downloads into a single status notification

[Copilot]

Context

Downloading multiple files at once produced a separate notification banner per file, cluttering the UI. This change groups all downloads triggered together into one consolidated status message with a collapsible file list.

Changes

state/interaction/actions.ts

• Added fullMsg?: string to StatusUpdate.data — carries the full untruncated message for "View more" expansion (replaces the earlier fileNames array approach)
• Extended processStart, processProgress, and processError signatures with optional fullMsg parameter

state/interaction/logics.ts (core change)

• Replaced per-file downloadRequestId process messages with a single groupProcessId for the entire batch
• Aggregate progress tracked across all concurrent downloads via one shared counter + throttled dispatcher
• Group cancel dispatches cancelFileDownload for each individual request
• Final status summarizes outcome: success count, partial failure with named files, or full cancellation
• Builds msg (header + first 3 file names as HTML) and fullMsg (header + all file names), only setting fullMsg when there are more than 3 files

components/StatusMessage/index.tsx

• Uses expandedIds state + toggleExpanded to track per-process expansion
• Displays msg by default; switches to fullMsg when expanded: displayMsg = isExpanded && fullMsg ? fullMsg : msg
• Shows a "View more" / "View less" button whenever fullMsg is present

// Before: N files → N separate banners
// After:  N files → 1 banner
// "Downloading 5 files.  42 MB set to download
//  • file_a.tiff
//  • file_b.tiff
//  • file_c.tiff"
//                              [View more]

Testing

• Updated logics.test.ts: "downloads multiple files" now asserts exactly one SET_STATUS action is dispatched for the batch, containing all fileId entries
• All 548 core unit tests pass; TypeScript and ESLint clean

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• production.int.allencell.org
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/biofile-finder/biofile-finder/node_modules/.bin/mocha --exit (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

The download stuff is just SOOOOOOOOO messy - I'm trying to clean it up which is something the AI agents are... not helpful at
