VS extension: batch all CLI calls into a single all --json invocation

[Copilot]

Multiple sequential CLI spawns on extension load caused multiple loader spinners and unnecessary latency. This replaces them with a single batched call that populates all view caches upfront.

CLI — new all command

• cli/src/commands/all.ts: runs calculateDetailedStats, calculateDailyStats, and calculateUsageAnalysisStats in parallel, then returns a single JSON envelope:

  { "details": {...}, "chart": {...}, "usage": {...}, "fluency": {...} }

VS extension — CliBridge batched fetch

• GetAllDataAsync(): runs all --json once, deserializes each top-level key, and populates all in-memory caches (_cachedStats, _cachedChartJson, _cachedUsageAnalysisJson, _cachedMaturity). Concurrent callers share the same in-flight Task — no duplicate processes.
• Individual Get*Async() methods now serve from cache when fresh; fall back to a per-command CLI call otherwise (backwards-compatible).

VS extension — single-spinner preload

• PrewarmAllViewsAsync() (called once during WebView init): shows one loading indicator, calls GetAllDataAsync(), then builds and caches rendered HTML for all five views (details, chart, usage, environmental, maturity). Tab switches after this point are instant with no additional spinners.

CI

• Added all --json validation step to both cli-build.yml and visualstudio-build.yml to catch regressions in the batched command.

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:

• teststorage.blob.core.windows.net
  • Triggering command: /opt/hostedtoolcache/node/20.20.1/x64/bin/node /opt/hostedtoolcache/node/20.20.1/x64/bin/node --require ./out/test/unit/vscode-shim-register.js --test-force-exit /home/REDACTED/work/github-copilot-token-usage/github-copilot-token-usage/vscode-extension/out/test/unit/backend-blobUploadService.test.js (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)

Original prompt

Issue Reference

Fixes #496

Problem Statement

The Visual Studio extension currently runs multiple CLI calls sequentially, causing multiple loader spinners to appear and resulting in a slower user experience. We need to optimize this by batching all the necessary data loading calls into a single grouped operation.

Requirements

1. Analyze the current implementation to identify where individual CLI calls are being made for loading data across different views
2. Design and implement a grouped call mechanism that can fetch all required data in one batch operation
3. Update the data loading logic to use the new grouped call approach
4. Ensure all views receive the data they need from the single batched call
5. Reduce the number of loader spinners shown to the user
6. Maintain the same functionality and data accuracy as the current implementation
7. Test that all views continue to display the correct information after the changes

Expected Outcome

• Single batched CLI call that retrieves all necessary data at once
• Reduced number of loader spinners displayed to the user
• Improved performance and user experience
• All extension views continue to function correctly with the same data

Technical Considerations

• Review the current CLI command structure and parameters
• Consider backwards compatibility with existing CLI versions
• Ensure error handling works correctly for the grouped call
• Update any related documentation or comments in the code
