[EPIC] Core services (abstractions)

[kirich1409]

Context

Cross-cutting protocols injected via ScanContext / CleanContext: FileSystem, CommandRunner, ResourceLockService, Logger, ProgressReporter, Clock, ConfigLoader. Public protocols in DevsweepCore, implementations in DevsweepCorePrivate.

Goals

• FileSystem protocol has NO removeItem / trashItem.
• CommandRunner accepts only argv-array, no shell-string, allowlist-validated.
• ResourceLockService uses NSRunningApplication + proc_listpids (P5).
• ProgressReporter rate-limited to 30 fps in impl (P9).
• ConfigLoader TOML-based.

Child tasks

Will be added as sub-issues after task batch.

Exit criteria

• Protocols + impls wired, unit tests for each pass.
