fix(build): update Foojay toolchain resolver for Gradle 9

feat: add SPI-based CredentialFrameworkProvider resolution to PkiBootstrap via ServiceLoader
feat: add PkiBootstrap.openCredentialFramework() for provider-driven credential framework initialization
feat: register BcX509CredentialFrameworkProvider in META-INF/services
feat: introduce ConfigurableProvider.validateConfig(ProviderConfig) as a standard provider-side validation hook
fix: move generic backendId consistency validation into the default ConfigurableProvider validation routine
fix: enforce provider-local configuration validation from allocate() so direct provider use remains safe outside bootstrap
fix: add provider-specific validateConfig implementations for bootstrap-managed providers based on consumed configuration keys
fix: report unknown provider configuration keys through provider-local JUL warning logs without exposing values
fix: fail fast on malformed consumed configuration values instead of silently falling back where invalid input would mask operator error
fix: extend PkiBootstrapTest to cover CredentialFrameworkProvider bootstrap path
fix: extend PkiBootstrapTest to cover async and crypto.workflow initialization paths whose prefixed properties are cleared in test setup
fix: add negative bootstrap/provider validation coverage for backend mismatch and invalid configured values
docs: expand JavaDoc and package-level documentation for CredentialFrameworkProvider bootstrap wiring, ServiceLoader usage, and configuration validation behavior
chore: keep PkiBootstrap independent from implementation-specific BC framework classes and preserve provider autonomy over validation and diagnostics

Closes #3 spent @2h

+ * Describes how a standard signature algorithm identifier maps to a concrete
+ * ZeroEcho signature context.
+ *
+ * <p>
+ * Standard external ecosystems such as X.509, PKCS#10, JCA, OpenSSL, or remote
+ * APIs often identify signature algorithms with canonical names such as
+ * {@code SHA256withRSA}, {@code SHA384withECDSA}, or {@code Ed25519}. ZeroEcho,
+ * by contrast, separates the key algorithm from the per-operation
+ * {@link ContextSpec}. This immutable helper bridges the two worlds by carrying
+ * all information needed to:
+ * </p>
+ * <ul>
+ * <li>import or compare the correct public-key algorithm,</li>
+ * <li>create a ZeroEcho signature context with an explicit, deterministic
+ * {@link ContextSpec}, and</li>
+ * <li>translate signature bytes between an external representation and the
+ * internal ZeroEcho representation when the two differ.</li>
+ * </ul>
+ *
+ * <h2>Representation model</h2>
+ * <p>
+ * For RSA PKCS#1 v1.5, RSA-PSS, Ed25519, and Ed448, the external and internal
+ * signature bytes are identical. ECDSA is different: X.509/JCA normally use
+ * ASN.1 DER encoded {@code SEQUENCE { r, s }}, while ZeroEcho ECDSA contexts
+ * use fixed-length IEEE P1363 bytes ({@code r || s}). The
+ * {@link SignatureRepresentation} enum models this distinction explicitly.
+ * </p>
+ *
+ * <h2>Security notes</h2>
+ * <ul>
+ * <li>This class never stores key material, plaintext, or signatures beyond the
+ * arguments passed to conversion methods.</li>
+ * <li>Conversion methods validate structure and length to prevent silent format
+ * confusion.</li>
+ * <li>The carried {@link ContextSpec} must be treated as part of algorithm
+ * semantics, not as an optional hint.</li>
