AICX v0.7.3

Added

• Unified multi-project scope handling across search, intents, semantic index,
  MCP, dashboard, and doctor surfaces so operators can narrow to one or more
  projects with the same contract everywhere.

Changed

• aicx store progress output is now bounded and human-readable: structured
  progress ticks remain machine-parseable while interactive terminals keep a
  stable three-line status view instead of flooding logs.

Fixed

• Gemini JSONL extraction now treats .jsonl files as session transcripts,
  preserving sessionId metadata and allowing aicx all to ingest Gemini
  sources alongside Claude, Codex, Junie, and CodeScribe.
• Junk corpus bucket slugs are covered so malformed or placeholder project
  names no longer leak into canonical project grouping.
