docs: define FileAutomation 1.0 roadmap and architecture

[JE-Chen]

Summary

This draft PR establishes the FileAutomation 1.0 product and engineering roadmap.

The goal is to evolve FileAutomation from a broad file-automation toolkit into a:

Universal File Layer + File Integrity + Data Pipeline Runtime

This PR is intentionally documentation/planning-first. It does not claim that the roadmap has already been implemented.

Scope covered

• UI 2.0 redesign direction
• Optional extras / dependency split
• Existing automatic PyPI publishing incorporated into a release-engineering plan
• Storage backend abstraction and common contract
• Integration/contract test strategy for all backends
• IntegrityMonitor 2.0
• Universal File / Storage / URI layer for other Integration-Automation projects
• Pipeline orchestration
• DAG runtime
• Eleven-backend target
• Cron scheduling
• Event-driven notifications
• Audit model
• MCP / AI semantic API
• CI/release strategy
• Documentation/discoverability
• Milestones and implementation issue breakdown
• 1.0 Definition of Done

Proposed implementation order

1. Architecture and public contracts
2. Storage API / URI / File abstraction
3. Extras and packaging
4. Backend contract + integration tests
5. IntegrityMonitor 2.0
6. Pipeline / DAG runtime
7. Scheduler + Events + Notifications + Audit
8. UI 2.0
9. MCP / AI
10. 1.0 stabilization and release

The GUI is deliberately not the first implementation milestone: it should consume stable application/domain APIs to avoid repeated rewrites.

Main architectural target

The project should converge on:

• File
• Storage
• StorageBackend
• Pipeline
• IntegrityMonitor
• event/audit primitives

while retaining FA_* actions as a compatibility/automation layer.

Deliverable

See docs/FILEAUTOMATION-1.0-ROADMAP.md for the complete roadmap, architecture rules, milestone checklists, backend testing strategy, UI direction, MCP strategy, and 1.0 acceptance criteria.

Next PRs

This roadmap should be implemented incrementally through focused PRs rather than one large implementation PR. Recommended first implementation PR: define the StorageBackend contract, URI model, and package/extras boundaries.
