Feature: DX Data Cloud Export/Sync

[bob-duetto]

Summary

Add ability to export gitflow-analytics data to DX-compatible format or sync directly.

Background

DX platform provides a PostgreSQL Data Cloud with 120+ tables. Having gitflow-analytics export to compatible formats would enable:

• Using DX dashboards with gitflow data
• Comparing metrics between tools
• Gradual migration path

Requirements

• Add dx_export module under src/gitflow_analytics/reports/
• Export commit data in DX schema format
• Export PR data in DX schema format
• Export DORA metrics in DX format
• Optional: Direct PostgreSQL sync to DX Data Cloud
• Add --export-format dx option to CLI

Data Mapping

gitflow-analytics	DX Table
Commits	git_commits
PRs	github_pulls
DORA metrics	dora_* tables
Authors	dx_users

Acceptance Criteria

• Export produces DX-compatible schema
• Import script for DX Data Cloud
• Validate data integrity post-import
• Document mapping in README

Priority

Low - Interoperability feature

Out of Scope

DX Data Cloud export/sync would require maintaining schema mappings against a third-party platform's 120+ table schema, which creates a significant maintenance burden. gitflow-analytics already exports to CSV/JSON which can be imported into any BI tool or PostgreSQL instance.

Closing as out of scope.
