[Breaking] Unify internal identity as auto_storage for 0.3.0

[swear01]

Goal

Ship Auto Storage 0.3.0 Alpha with one canonical internal identity instead of retaining magic_storage compatibility identifiers.

Canonical identity

• Display name: Auto Storage
• GitHub/local repository: Auto_Storage
• Mod ID and resource namespace: auto_storage
• Java package: com.swear.autostorage
• Main mod class: AutoStorage
• Jar basename: auto_storage
• Version: 0.3.0

Scope

• Rename Java packages/classes/source roots and every main/fixture import.
• Rename registries, resources, translations, recipes, tags, structures, Patchouli book IDs, network IDs, commands, configs, SavedData/storage keys, GameTest namespaces, fixture mod IDs, system properties, scripts, CI/CD artifacts, Prism test/deployment identifiers, generated metadata, and current docs.
• Remove current magic_storage aliases/fallbacks. This release intentionally does not migrate 0.2.0 worlds/configs.
• Keep third-party proper nouns such as Terraria's Magic Storage unchanged.
• Update Modrinth and CurseForge source/issues links to the canonical GitHub repository.
• Publish a GitHub wiki whose player guide tracks the in-game Patchouli manual.

TDD / acceptance

• Add a failing identity contract first and confirm RED before production changes.
• No active source/config/resource/script path uses old internal identifiers after the rename, except explicit historical release evidence and third-party proper nouns.
• ./gradlew build, minimum/latest EMI compilation, all base/fixture/matrix GameTests, Python tests, and datagen drift remain green.
• Generated jar is build/libs/auto_storage-0.3.0.jar and contains the expected auto_storage namespace and com.swear.autostorage classes.
• Dedicated server remains free of client-only linkage.
• Active docs explicitly record the 0.3.0 breaking boundary and lack of 0.2.0 migration.

[swear01]

Completed in 297b7a2.

• Renamed the canonical mod ID to auto_storage and Java package to com.swear.autostorage.
• Set version to 0.3.0 and artifact to auto_storage-0.3.0.jar.
• Renamed resources, fixture namespaces, scripts, CI/CD, Prism GUI identifiers, and documentation.
• Added explicit 0.3.0 breaking-change notes; 0.2.x worlds are intentionally not migrated.
• Updated Modrinth and CurseForge links and published the GitHub Wiki manual.
• Full local verification and independent review passed.
• GitHub CI run 30519806244 passed all required build, GameTest, optional-mod compatibility, script-test, datagen, and artifact gates.
