feat: add JSON-LD download and consolidate report download actions

[jfrench9]

Summary

This PR introduces JSON-LD serialization support for reports and improves the download experience by consolidating multiple download buttons into a single unified dropdown menu.

Changes

Report Viewer Enhancements (src/app/(app)/reports/[id]/content.tsx)

• New Download JSON-LD action: Users can now export reports in JSON-LD format directly from the report viewer, enabling structured data interoperability and semantic web compatibility.
• Consolidated Download dropdown: Previously separate download buttons (e.g., PDF, and now JSON-LD) have been collapsed into a single "Download" dropdown menu, reducing toolbar clutter and providing a cleaner, more scalable UI pattern for future export formats.

Dependency Updates

• Bumped @robosystems/client from previous version to 0.3.36, which likely includes the underlying API support for JSON-LD report serialization.

Key UI/UX Improvements

• 🎯 Reduced visual clutter: Multiple download buttons replaced with a single dropdown, simplifying the report viewer toolbar.
• 📦 JSON-LD export: Enables users to download report data in a standardized linked data format, useful for data integration, archival, and machine-readable workflows.
• 🔄 Scalable pattern: The dropdown approach makes it straightforward to add additional export formats in the future without further UI changes.

Breaking Changes

None. This is an additive feature change. Existing download functionality is preserved within the new dropdown UI.

Testing Notes for Reviewers

1. Download dropdown behavior: Navigate to a report at /reports/[id] and verify the download button renders as a dropdown with all available options (including JSON-LD).
2. JSON-LD download: Click the "Download JSON-LD" option and verify:
   • The file downloads successfully with appropriate filename and .jsonld or .json extension.
   • The downloaded content is valid JSON-LD (check for @context, @type fields as applicable).
3. Existing download actions: Confirm that any previously available download formats (e.g., PDF) still function correctly within the new dropdown.
4. Edge cases: Test with reports that may have missing or incomplete data to ensure the serialization handles these gracefully.
5. Dropdown accessibility: Verify the dropdown can be navigated via keyboard (Tab, Enter, Escape) and that aria attributes are present.

Browser Compatibility Considerations

• The dropdown component should be tested across Chrome, Firefox, Safari, and Edge.
• Verify that the file download (likely using Blob / URL.createObjectURL or an anchor download) works consistently across browsers, especially Safari which can have differing behavior with programmatic downloads.
• Ensure no issues with popup blockers intercepting the download action.

Overview

Overall this is a solid, well-structured addition. The two-strategy download pattern (presigned URL redirect for JSON-LD, blob/anchor for XBRL) is architecturally sound and the individual concerns below are mostly minor. A few things worth addressing before merge.

---

Issues

1. Version bump violates project convention (medium)

package.json bumps @robosystems/client from 0.3.34 → 0.3.36. The CLAUDE.md explicitly states:

Never bump versions in package.json / pyproject.toml — version bumps are owned by the user on publish.

The underlying SDK functionality may require this bump, but the version pin should be reverted and the user should own that change separately. Fix this →

---

2. Redundant disabled on DropdownItem (low)

content.tsx lines 342–353

<Dropdown
  disabled={isDownloadingBundle || isDownloadingXbrl}  // ← whole dropdown locked
  ...
>
  <DropdownItem
    onClick={handleDownloadBundle}
    disabled={isDownloadingBundle}   // ← dead — parent is already disabled
  >
  <DropdownItem
    onClick={handleDownloadXbrl}
    disabled={isDownloadingXbrl}     // ← dead — parent is already disabled
  >

When the parent Dropdown is disabled, individual DropdownItem disabled props are never evaluated. The per-item disabled props are dead code and add misleading noise. If the intent was to let users click the non-loading item while the other is in-flight (e.g., click XBRL while JSON-LD is downloading), then the parent disabled condition needs to change instead — but that introduces a UX inconsistency (spinner shows with an open dropdown). Current behavior is conservative and fine, just drop the per-item disabled. Fix this →

---

3. Comment volume exceeds project conventions (low)

content.tsx lines 93–99, 114–119, 144–148, 165

CLAUDE.md says: "Default to writing no comments. Only add one when the WHY is non-obvious... Don't explain WHAT the code does."

The added comment blocks are thorough but several explain the what rather than the why. The most defensible comments are:

• Cross-origin behavior of window.location.href vs <a download> (line 117–119) — keep
• The setTimeout revocation delay note (line 165) — keep

The large header docblock on handleDownloadBundle (lines 114–142) and the paragraph on the XBRL approach (lines 144–148) should be condensed to a single line each (or removed entirely if the function signature and variable names are self-explanatory).

---

4. PR description omits XBRL (low — documentation only)

The PR title and body describe JSON-LD as the new addition and do not mention the XBRL 2.1 download. The diff clearly adds both handleDownloadBundle and handleDownloadXbrl. The title/description should be updated before merge so reviewers and the git log reflect what actually shipped.

---

Things Done Well

• Two-strategy approach is correct. window.location.href is the right choice for a cross-origin presigned URL (the download attribute on <a> elements is ignored for cross-origin URLs in all major browsers). The blob/anchor approach for the XBRL streamed response is also the right call.
• Shared downloadError state works. Each handler calls setDownloadError(null) at the top, so stale errors don't leak across attempts.
• 5-second revocation delay on the XBRL object URL is a good practice — immediate revocation can abort the download in some browsers.
• generationStatus === 'published' gate on the dropdown is correct; no point offering downloads on a report still generating.
• Error surfacing strategy is solid — surfaces the backend 404 message for stale reports rather than a generic string.
