v2.1.0

What's New

Read-Only Mode

New -readonly flag / GOBUILDCACHE_READONLY env var that suppresses backend write operations (Put/Touch) while allowing reads (Get/Has) to pass through normally. This lets CI workers (e.g., PR builds) consume the shared S3 cache without polluting it. The local disk cache continues operating with full read-write access.

• Put and Touch become no-ops at the S3 layer — no async goroutines spawned
• Clear returns an error so destructive operations are never silently ignored
• Read-only stats reported in both human-readable and machine-readable output

Other

• Fix test workflow for fork: update actions, use local S3 tests
