feat: add cortex-code transcript provider

[jamescha-earley]

Summary

• Adds a new cortexCode transcript provider that discovers and parses Snowflake Cortex Code conversation transcripts from ~/.snowflake/cortex/conversations/*.json
• Scopes discovery to workspace via working_directory matching, detects running/idle/completed status from last_updated recency and active tool calls
• Extracts connection name, message count, tool call count, and session type as metadata; registers as a default provider alongside cursor, claude-code, codex, and opencode

Test plan

• 41 new tests across 4 test files (schemas, discovery, transcripts, provider integration)
• npm run check passes (biome + typecheck + 262 tests across 36 files)
• Build succeeds with ESM, CJS, and DTS outputs including new providers/cortex-code entry point
• Tested locally against 297 real Cortex Code conversation files — correct discovery, parsing, metadata extraction, and status detection

Checklist

• Tests added
• npm run check passes
• Docs updated (README.md — providers list, entry points, provider count)
• CHANGELOG updated (Unreleased section)

Summary by cubic

Adds a new cortexCode transcript provider that discovers and parses Snowflake Cortex Code session JSONs and normalizes them into agent snapshots. It’s included in the default provider set for observers.

• New Features

  • Discovers sessions from ~/.snowflake/cortex/conversations/*.json, scoped by working_directory.
  • Detects running/idle/completed using last_updated recency and active tool calls.
  • Extracts metadata: connection name, message count, tool call count, session type; builds task summary from first user prompt.
  • Caches file headers by mtime to skip unchanged files; JSON file watch with 150ms debounce.
  • Public entry: @agentprobe/core/providers/cortex-code; registered as a default provider; 41 tests added.

• Migration

  • No changes required—createObserver() now includes cortexCode() by default.
  • To customize, import cortexCode from @agentprobe/core/providers/cortex-code and pass options like cortexHomePath, maxFiles, or disable watch.
