/**
 * Validates that the static segments in currentPath match the corresponding
 * segments in targetSegments. This ensures we only extract dynamic parameters
 * that are part of the target pathname structure.
 *
 * Segments are compared literally - interception markers like "(.)photo" are
 * part of the pathname and must match exactly.
 *
 * @example
 * // Matching paths
 * currentPath: ['blog', '(.)photo']
 * targetSegments: ['blog', '(.)photo', '[id]']
 * → Returns true (both static segments match exactly)
 *
 * @example
 * // Non-matching paths
 * currentPath: ['blog', '(.)photo']
 * targetSegments: ['blog', 'photo', '[id]']
 * → Returns false (segments don't match - marker is part of pathname)
 *
 * @param currentPath - The accumulated path segments from the loader tree
 * @param targetSegments - The target pathname split into segments
 * @returns true if all static segments match, false otherwise
