Fixes

• Cache keys include captured values, method targets and generic arguments; non-relational providers (InMemory, Cosmos) no longer share one key.
• MemoryCacheProvider: replacing an entry no longer drops its tag tracking.
• Entity detection covers query roots in joins and subqueries.
• Invalidation uses EF metadata for changed types (proxies, inheritance, owned types, many-to-many).
• Reference-counted stampede lock; First/Single are protected too.
• Pending invalidations are bound to the DbContext: kept after a failed save inside a transaction, no leak on dispose; TransactionScope invalidates on commit.
• Redis: chunked tag deletes, tag-set TTLs only extended, sliding expiration honoured, ClearAsync skips replicas.
• DefaultOptions and AutoInvalidation configuration are honoured.

Changes

• Cached queries execute with AsNoTracking (identity resolution preserved).
• AddCacheInvalidation throws when no DbContextOptions is registered.
• New public CacheTags.ForEntity() / ForEntity(Type).
• EnableLogging and ICacheInvalidator.RegisterCacheEntry marked [Obsolete].
• XML docs enforced for library projects; README and CHANGELOG corrected.

Demo

• Fixed tag and tenant-filter bugs and the Docker build context.
• Redis provider switch, docker-compose Redis service, new scenarios (subquery, SkipIf, sliding/IgnoreContext, ExecuteUpdate, TransactionScope, background job) with integration tests.
