Add content_hash(resource, *, algorithm='sha256') -> str to the ResourceHandler protocol and all handler implementations: - Protocol: new content_hash method on ResourceHandler (protocol.py) - BaseResourceHandler: default impl hashes file content or directory entry names; returns EMPTY_CONTENT_HASH sentinel for missing resources - GitCheckoutHandler: hashes git rev-parse HEAD through the requested algorithm for consistent digest format - FsDirectoryHandler: recursive walk hashing sorted relative paths and file contents (content-only, ignores metadata) - DevcontainerHandler: hashes devcontainer.json config file - DatabaseResourceHandler: hashes connection string; for SQLite file-based DBs, hashes the database file content - _DefaultHandler: delegates to BaseResourceHandler EMPTY_CONTENT_HASH sentinel is the SHA-256 of empty input (e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855). Hash algorithm is configurable via the algorithm parameter (default sha256, accepts any hashlib.new()-compatible name). Behave tests (10 scenarios): sentinel for missing/nonexistent, determinism, different content produces different hash, fs-directory recursive hash with change detection, git-checkout hash, configurable algorithm (sha256 vs sha512), protocol compliance for all 4 handlers.
