Model Context Protocol server for DeepSource

/**
 * @fileoverview Branded types for the DeepSource MCP server
 *
 * This module defines branded types to enforce type safety for string-based identifiers.
 * Branded types help prevent mixing different string identifiers that share the same primitive type.
 * For example, a ProjectKey and RunId are both strings, but they represent different concepts.
 * Using branded types ensures that functions expecting a ProjectKey cannot accept a RunId.

 * Converts a string to a ProjectKey branded type
 *
 * This helper function safely converts a regular string to the ProjectKey branded type.
 * ProjectKey is used to type-safely represent DeepSource project identifiers throughout
 * the codebase, ensuring they cannot be accidentally mixed with other string identifiers.
 *
 * @example
 * ```typescript
 * // Convert a project ID string to a branded type
 * const projectKey = asProjectKey('abc123');
 *
 * // Use with a function requiring ProjectKey parameter
 * const project = getProjectDetails(projectKey); // Type-safe
 *
 * // This would cause a compile error:
 * const runId = asRunId('xyz789');
 * getProjectDetails(runId); // Error: Type 'RunId' is not assignable to type 'ProjectKey'
 * ```
 *
 * @param value - The string to convert to a ProjectKey
 * @returns The same string, but with the ProjectKey branded type
 * @public
 */

 * Converts a string to a RunId branded type
 *
 * This helper function safely converts a regular string to the RunId branded type.
 * RunId is used to type-safely represent DeepSource analysis run identifiers (UUIDs)
 * throughout the codebase, ensuring they cannot be accidentally mixed with other identifiers.
 *
 * @example
 * ```typescript
 * // Convert a run UUID string to a branded type
 * const runId = asRunId('61c38bcc-c546-4694-be79-123456789abc');
 *
 * // Use with a function requiring RunId parameter
 * const run = getRunDetails(runId); // Type-safe

 * @returns The same string, but with the RunId branded type
 * @public
 */

 * Converts a string to a CommitOid branded type
 *
 * This helper function safely converts a regular string to the CommitOid branded type.
 * CommitOid is used to type-safely represent git commit hashes throughout the codebase,
 * ensuring they cannot be accidentally mixed with other string identifiers.
 *
 * @example
 * ```typescript
 * // Convert a commit hash string to a branded type
 * const commitOid = asCommitOid('6a8e94c82f948d6f2932e905e83fe60166a1c70a');

 * // Use with a function requiring CommitOid parameter

 * @returns The same string, but with the CommitOid branded type
 * @public
 */

 * Converts a string to a BranchName branded type
 *
 * This helper function safely converts a regular string to the BranchName branded type.
 * BranchName is used to type-safely represent git branch names throughout the codebase,
 * ensuring they cannot be accidentally mixed with other string identifiers.
 *
 * @example
 * ```typescript
 * // Convert a branch name string to a branded type
 * const branchName = asBranchName('feature/add-new-metrics');
 *
 * // Use with a function requiring BranchName parameter
 * const branchDetails = getBranchDetails(branchName); // Type-safe

/**
 * Converts a string to an AnalyzerShortcode branded type
 *
 * This helper function safely converts a regular string to the AnalyzerShortcode branded type.
 * AnalyzerShortcode is used to type-safely represent DeepSource analyzer identifiers
 * (like "python", "javascript", etc.) throughout the codebase, ensuring they cannot
 * be accidentally mixed with other string identifiers.
 *
 * @example
 * ```typescript
 * // Convert an analyzer code string to a branded type
 * const analyzerCode = asAnalyzerShortcode('python');
 *
 * // Use with a function requiring AnalyzerShortcode parameter
 * const analyzerDetails = getAnalyzerDetails(analyzerCode); // Type-safe

/**
 * Converts a string to a GraphQLNodeId branded type
 *
 * This helper function safely converts a regular string to the GraphQLNodeId branded type.
 * GraphQLNodeId is used to type-safely represent internal GraphQL node identifiers
 * throughout the codebase, ensuring they cannot be accidentally mixed with other identifiers.
 * These IDs are typically used with the Relay-style GraphQL interface.
 *
 * @example
 * ```typescript
 * // Convert a GraphQL node ID string to a branded type
 * const nodeId = asGraphQLNodeId('QWNjb3VudDoxMjM0NQ==');
 *
 * // Use with a function requiring GraphQLNodeId parameter
 * const node = getNodeById(nodeId); // Type-safe

 * @returns The same string, but with the GraphQLNodeId branded type
