Assisted update command (pollora:update)

[ogorzalka]

Phase 4 — Mise à jour assistée (v14.0)

Problem

No assisted update mechanism. Developers must manually update composer.json and manage breaking changes.

Proposed solution

Interactive pollora:update Artisan command that:

1. Checks installed version vs latest available (reuse VersionComparator)
2. Displays changelog for intermediate versions
3. Highlights breaking changes
4. Updates the constraint in composer.json
5. Runs composer update pollora/framework
6. Executes migrations if needed

Key files

• src/VersionCheck/ (reuse existing checker)
• New: src/Update/UI/Console/UpdateCommand.php

Target version

v14.0
