Pull request overview

Adds a standalone TypeScript utility under profile-long-calls/ to download user-cache zips from S3, extract long_calls.txt, ingest the data into a local SQLite DB, and print aggregate “worst offender” IPC-call performance reports.

Changes:

• Introduces long-calls-analyzer.ts (S3 listing/download, zip extraction, SQLite ingest, and reporting).
• Adds local tooling/config for building/running/debugging the analyzer (tsconfig, package.json, VS Code launch config, Yarn config).
• Updates .gitignore to exclude build output (dist/) and the generated SQLite DB.

• Same as above: affected_users is computed as COUNT(DISTINCT source_id), which counts sources/zips rather than users. If the output is intended to be per-user, join sources and count distinct username (handling NULLs appropriately) or rename the output to avoid implying it’s user count.

          call_name,
          SUM(is_freeze)            AS freezes,
          COUNT(DISTINCT source_id) AS affected_users,
