Add generic enterprise-grade features to the orchestrator, enabling Unity projects with
complex CI/CD pipelines to adopt game-ci/unity-builder with built-in support for:
- CLI provider protocol: JSON-over-stdin/stdout bridge enabling providers in any language
(Go, Python, Rust, shell) via the `providerExecutable` input
- Submodule profiles: YAML-based selective submodule initialization with glob patterns
and variant overlays (`submoduleProfilePath`, `submoduleVariantPath`)
- Local build caching: Filesystem-based Library and LFS caching for local builds without
external cache actions (`localCacheEnabled`, `localCacheRoot`)
- Custom LFS transfer agents: Register external transfer agents like elastic-git-storage
(`lfsTransferAgent`, `lfsTransferAgentArgs`, `lfsStoragePaths`)
- Git hooks support: Detect and install lefthook/husky with configurable skip lists
(`gitHooksEnabled`, `gitHooksSkipList`)
Also removes all `orchestrator-develop` branch references, replacing with `main`.
13 new action inputs, 13 new files, 14 new CLI provider tests, 17 submodule tests,
plus cache/LFS/hooks unit tests. All 452 tests pass.
